In the village of Oberrieden, on the shores of Lake Zurich, Katharina Locher invites us to discover a veritable little gem. It's not only the size of the garden that makes it so unusual, but also its situation: right in the heart of an agricultural area. A rare setting for an ornamental garden.

Strolling through the streets of old Berne, it's difficult to imagine that nearby grow a plethora of fruit, trees and vegetables. From the Cathedral Square, you can just make out a large city garden below. An area of greenery that is open to anyone who wants to come and garden.

We're off to the canton of Grisons, in a valley known for its innumerable villages perched high on the hillsides. The village of Rothenbrunnen hides an idyllic garden, a little area of mountain nestling between the houses.

Welcome to Hauterive Abbey. An imposing monument, it was built some nine hundred years ago on the banks of the River Saane, near Fribourg, in a landscape enclosed by a sandstone cliff. This baroque building is today home to eighteen Cistercian monks who care for a superb garden
