The gardens of Castle Trauttmansdorff and Princess Sissi. On the sunny slope above Merano, where Empress Sissi once used to stroll, the gardens of Castle Trauttmansdorff extend. Over 12 hectares divided into four vegetation zones, the garden features different environments such as the broadleaf and coniferous forest habitat of America and Asia, the summer gardens of the Mediterranean belt, the typical landscapes of South Tyrol, and numerous examples of green architecture.
