Time Team descend on the Isle of Mull at the invitation of two local amateur archaeologists to investigate a mysterious set of earthworks in a forest near Tobermory. Could they be the remains of a chapel from the time of St Columba?

In deepest Wales lies an extraordinary site, with a Megalith, a Neolithic tomb, a Norman watchtower, early Christian symbols, and a natural spring. From this spring, the landowner has recovered an astonishing variety of coins, sculptures and jewelry. It is almost too good to be true, rather like an ancient theme park. So begins one of Time Team's most remarkable digs. Geophysics shows no structure anywhere on the site. The megalith is far too shallow to have stayed upright for thousands of years. And when the team unearth a sword, they start to get suspicious. They are joined by Celtic ritual expert Miranda Green, architectural historian Will Hughes, and Iron Age specialist Ian Stead. Results show that the site has been 'salted' and the finds have all been placed or build between the 19th century and as late as the 1980s. More info can be found at Llygadwy.

A Byzantine brass bucket was found during a 3-day live dig in a Saxon cemetery a year ago. Time Team returns to find out more about the people who lived and died here. Metal detectorists are called in to find non-ferrous metals, to complement Geophysics' magnetometer survey. They are joined by Anglo-Saxon specialist Andrew Reynolds, paleopathologist Alice Roberts and celebrity Sandi Toksvig. Sandi's ancestors were from Jutland, and Robin Bush argues that this whole area of Hampshire was actually occupied by Jutes before they were defeated by the Saxons under King Cadwalla in 686 AD. Ray Walton replicates a brass bucket, complete with inscriptions and silvering, from scratch. Osteoarchaeologist Margaret Cox tries to make sense of the burials including rare double burials – one of which uniquely has a child placed between two men. Finds include weapons and an exquisite enamelled belt buckle; and three more of the mysterious buckets, which all fit one inside the other.

Ancaster has yielded numerous Roman finds as well as a large cemetery with several sarcophagi from the period. In addition, the church is known in British archaeology for a Roman inscription dedicated to the deity Viridius. Phil finds the cemetery level, while Carenza discovers a layer filled with jumbled up human remains mixed with other bones. In the cemetery, Phil eventually uncovers the lid of a possible sarcophagus, and its excavation could thus require certain precautions due to the potential for lead poisoning and presence of biological hazards. However, the object proves to be a cist burial, as well as hazard-free. Incredibly, one of the cist slabs also turns out to contain yet another inscription to the god Viridius. In the end, the archaeologists suggest that the massive defences were ordered to be put up by the Roman central administration in Britain, and completely disrupted the original town layout.

It is 40 years since amateur archaeologists dug up Roman remains near Ermine Street, now hidden beneath Cheshunt Park. Time Team tell the story of the original excavation, using the detailed plan to conduct their own investigation. They believe the site's proximity to the road is the key to this dig. With some brilliant work by Stewart and John, they soon locate part of the road. Though frustratingly they cannot find any trace of it beneath the surface, they do find a brewery and possibly a pub. The brewing process is described by ancient technology expert Peter J. Reynolds. They conduct a mini-experiment comparing Roman surveying techniques with Henry's modern equipment. They are also joined by Roman experts Rosalind Niblett and Harvey Sheldon.

Revisiting digs that produced rare and fine jewellery, gold coins, huge and intricate mosaics - and some extraordinary archaeological fakery - Mick Aston, Phil Harding and Helen Geake defend and debate their choices for Time Team's greatest discoveries.

In 300 A.D. Corinium Dobunnorum was England's wealthiest city next to Londinium. Now it's the pleasant Gloucestershire town of Cirencester, and Time Team are visiting the leafy suburban Chester Street, where they hope the back gardens will yield clues about the bustling Roman city and its main highway, Ermine Street. Could a Roman temple have occupied this site - or even rarer, an early Christian church? They need to knock on a few doors to ask about digging up their plots. There is a bottle of champagne for anybody who can find a tessellated pavement. They are joined by Roman architectural historian Tom Blagg, coin expert Richard Reece and mosaic expert David Neal. The Ermine Street Guard offer Tony venison stew, and use a wooden crane to erect a stone column, fashioned by mason Giles MacDonald. In the public presentation, Stewart outlines a picture of the whole city, ably assisted by Victor's drawing. Among many Roman finds are coins, a brooch, a spoon and a bone die.

The team dig for Roman remains in Greenwich Park, London. They are joined by Hedley Swain from the Museum of London, Harvey Sheldon from the University of London and Mark Hassel from University College, London. Chris Owen (reconstructor) demonstrates Roman plastering techniques and ingredients, and paints a fresco with Victor. A remarkable find creates much excitement, boosting their hopes of identifying a Roman temple. Stewart suggests that Watling Street may have run through the park.

Two years ago, local archaeologist Kevin Trott discovered Roman remains in a trench being dug for a water pipe. Unfortunately the trench had to be closed, and now Time Team are having trouble finding it. While Phil and the diggers look for the original trench, a full-scale field-walking exercise reveals many finds, both Roman and Iron Age; including a lot of bronze jewellery, seeming to show industrial activity. There are hints that enamelling was carried out here, so they decide to make their own enamelled hare brooch. Mick and Tony visit a nearby Roman villa with a detailed mosaic floor. On day three, Stewart spots some potential earthworks in a neighbouring field; so they decide to dig some exploratory trenches there. They end up with examples of activity from the Bronze Age, Iron Age, Roman occupation, and Anglo-Saxon period. To cap it all, at the end of day three they find a rare Iron Age burial. The team are joined for the first of many digs by Anglo-Saxon expert Helen Geake.

Derek Batten bought a plot of land advertised as a castle and moat; but there is little sign of a castle other than a tree-covered mound surrounded by a huge ditch. So he has asked Time Team to sort it out. Because the site is a scheduled ancient monument, the team have to get permission from English Heritage for strictly limited excavations. To complicate matters further, Tony has to adjudicate on a long-running boundary dispute. The team is joined by castles expert Philip Dixon. Phil Harding gets kitted-out in chainmail as a Saxon footsoldier, facing a mounted Norman warrior on a Spanish stallion. The site is finally identified as a ringwork castle, built on a previous Saxon structure around the time of the Norman Conquest.

The medieval castle of Beaudesert in Henley-in-Arden suddenly vanished without trace, leaving a single stone on top of a mound. The people want to know what it looked like. "The Mount" as it's called by the locals, is a popular beauty spot and has suffered from erosion. Also, as it's a scheduled monument, there are limits to what digging can take place. The castle was built by the de Montforts in the early 12th century. Henry and Stewart create a simple 3D clay model of the building, which follows the natural contours of the hill. It looks as if the castle was demolished and the pieces sold off in the 15th century. Using authentic tools, bowyer Steve Ralphs makes a medieval longbow, which is tested against a crossbow of a similar period. Castles expert Sarah Speight describes daily life in the castle. Finds include a section of carved pestle and mortar.

The crumbling ruins of Codnor Castle are a sad remnant of the imposing home of the De Grey family - knights who saw action in almost every important medieval battle including the crusades and Agincourt. Today Codnor Castle lies in ruins and there's almost nothing known of how it looked in its prime. As the remains above ground get an overdue renovation, the Time Team risk the dangers of hidden mine shafts in the Derbyshire coalfields to dig into the heart of a building that once dominated the landscape to trace the castle's history. It lives up to the team's hopes as they strike gold with a 600-year-old gold noble coin as well as uncovering a huge round tower and, for the first time in the history of the programme, a drawbridge.

In Sutton Courtenay Tony Robinson and the Team investigate a set of buildings once occupied by Anglo Saxon royalty. It's the rarest of archaeological sites and uncovers the biggest Saxon building ever discovered in Britain. Aerial photography of an apparently featureless Oxfordshire field revealed crop marks that suggested to archaeologists it was once the site of an impressive collection of 1,400-year-old buildings; but Time Team's digging expertise was needed to verify this. The trenches are big and the archaeology complicated but slowly the Team begin to build up a picture of life here over 1,000 years ago, with the help of heroic Saxon poetry. As well as stunning finds and the perplexing possibility that they have uncovered an Anglo Saxon totem pole, the archaeologists also discover a culture where heroism, story telling and drinking go hand in hand, and learn the finer points of how to insult your colleagues in Old English.

Tony Robinson and his team celebrate their 200th dig. Jane Marchand from Dartmoor National Park Authority was alerted by a walker to standing stones peering out of an East Devon reservoir at low level. This is Francis Pryor's dream site, but Mick has also been interested in Dartmoor for some time. They have stone circles, stone rows and cairns apparently dating from 3000 to 1500 BC. There is a central mound which interests Francis, and which Phil thinks is Stone Age, thus pre-dating the other monuments. But the cairns may be recent, throwing into doubt the dating of the other features. This is cultivated farmland, atypical of Dartmoor's usual bleak landscapes. John is dubious about getting any meaningful geophysics results, but proposes nevertheless to wheel his trolley through the mud. Stewart and Henry create a 3D image of the prehistoric landscape. Phil teaches Matt his favourite activity, flint-knapping.

Tony and the Team get a unique opportunity to dig at an army firing range at High Ham in Somerset and investigate a series of mosaics first discovered 150 years ago. Everything indicates a Roman villa, though perhaps not on such a grand scale. The inhabitants may have been Romanised Britons, living from the 2nd to the early 5th century. Matt volunteers as a slave for the day. When the cold east wind sets in, Phil and the other diggers temporarily "down tools". They are joined by Martin Brown from the Defence Estates and Roman finds specialist Philippa Walton.

Tony Robinson heads to Jersey to investigate the origins of Mont Orgueil Castle. Today's castle is a Tudor structure built on earlier foundations, and it's that early castle, built by King John, that the Team are looking for.

Tockenham village, in the Wiltshire countryside. Despite the fact that there are no Roman remains in Tockenham, the village's 15th century church, St Giles, has a small pagan Roman statue embedded in one of its outer walls.

3 days of live excavation. The weekend ended with evidence of a Romano-British villa complex that is one of the largest ever found in Britain. This programme is an edited version of that weekend. They discover that the villa dates from the very first days of the Roman occupation. Amongst their new finds is an entire, untouched Roman water course.

The team have their work cut out in the Cambridgeshire fenland, looking for remnants of an ancient culture in the flat landscape. The long wooden track would function as a barrier, defence and ritual passage where votive offerings were placed in the water. At the end of it they hope to find a barrow - a circular Bronze Age burial mound. Dave Chapman constructs a bronze axe in a primitive furnace; while wood expert Maisie Taylor looks for a suitable handle in nearby woodland.

The team are invited to investigate the officers' mess of a military base in Bedfordshire, once home to monks and nuns of a 14th century Gilbertine Order. It was an experiment in unisex living. Jenni of Time Team volunteers to live like a nun during the dig, and is initiated by nunnery expert Roberta Gilchrist. John Ette from English Heritage monitors proceedings, and they are also joined by historian Richard K. Morris and osteoarchaeologist Margaret Cox. Robin Bush tells the miraculous tale of the Nun of Watton.

Hoping to uncover Bronze Age burials, the team descend on a disused airfield. But initial finds suggest the Iron Age, while geophysics shows plenty of circles and some larger rectangular enclosures. Jacqui Wood makes prehistoric cheese, and cooks a fish stew. Bronze Age enthusiast Francis Pryor gets excited about some faint track marks. They are joined by Malcolm Atkin and Robin Jackson from Worcestershire County Council, Ian George from English Heritage, and Iron Age expert Jeremy Taylor.

Tony Robinson and the Team find themselves lost in the mists of a Welsh forest as they investigate one of the biggest castles in Britain. Their task is to investigate the castle's mysterious interior and find out how this impressive structure fitted into a network of fortresses built by powerful English barons 700 years ago.

An eagle-eyed forest ranger spotted bits of Roman building poking out from the forest floor in Cambridgeshire's Bedford Purlieus Wood.

The team go to the Somerset levels in search of a 4,000-year-old wooden trackway. The quickest way to get across the marshes that used to exist here in the Bronze and Iron Ages was across wooden walkways. Now the team hope to find evidence of these footbridges.

The team are intrigued that an Anglo-Saxon cemetery should contain Roman pottery. They are joined by archaeologist Naomi Field, Maggie Darling (Roman pottery expert), Martin Welch (Anglo-Saxon expert), Irit Narkis (archaeological conservator), and Kevin Leahy (Anglo-Saxon cemeteries expert).
