Our journey starts with Hohenzollern Castle, the cradle of the last Prussian reigning family and a symbol of their power: an eagle's nest, perched on a green peak. After a trip to a snail farm, a culinary speciality of Swabia, we discover Ludwigsburg Castle, a small pleasure pavilion that gradually became one of Europe's largest baroque residences. Equivalent to Versailles in size, it houses a sumptuous theatre, whose restorer takes us behind the scenes. We then take a trip up the vineyard-bordered Neckar River, and discover Mainau Island on Lake Constance, which in the warmer months, turns into a sea of flowers.
