Just behind the Great Church, the Reformed College is one of the oldest centres of learning in Hungary, founded in 1538 and continuously operating ever since. The current yellow neoclassical building dates from the early nineteenth century and houses both the working theological university and a museum that opens up the college's history to visitors.
The library is the highlight: 600,000 volumes, including illuminated manuscripts, sixteenth-century printed bibles, and an exceptional collection of Hungarian first editions. Guided tours take in the chapel, the oratorium where the 1849 Hungarian parliament met, and the schoolrooms preserved as they would have looked in the eighteenth century.
