Kloster Maulbronn, in the little town of Maulbronn, 18 km (11 mi) northeast of Pforzheim, is the best-preserved medieval monastery north of the Alps, with an entire complex of 30 buildings on UNESCO's World Heritage list. The name Maulbronn (Mule Fountain) derives from a legend. Monks seeking a suitably watered site for their monastery considered it a sign from God when one of their mules discovered and drank at a spring. The Kloster is also known for inventing the Maultasche, a kind of large ravioli. The monks thought that by coloring the meat filling green by adding parsley and wrapping it inside a pasta pocket, they could hide it from God on fasting days. Today the Maultasche is the cornerstone of Swabian cuisine. An audio guide in English is available.
