The Tübinger Stift, a Lutheran seminary attached to the university, has produced an extraordinary roll-call of German thinkers, including the philosophers Hegel and Schelling and the poet Hölderlin (all three were roommates in the 1790s). The yellow building on the riverbank, with its long Renaissance frontage, was originally an Augustinian monastery and was taken over by the Württemberg Reformation in the 16th century.
The Stift is still in use as a hall of residence for theology students. It is rarely open to the public, but the exterior and the courtyard are worth a look — and the entire stretch of the Neckar front is the most photographed view in Tübingen.
