Eger Lyceum, Library and Camera Obscura

The Lyceum is a great 18th-century Baroque building opposite the basilica, now home to the university. Inside you can visit the archbishopric's library, with a painted ceiling and very valuable documents, and, in the tower, the observatory and science centre, with an 18th-century camera obscura that the tourist office presents as the oldest on the continent that still works: a mirror and a lens project the town live onto a table in the darkened room. It is at Eszterházy tér 1. Check opening hours and prices at the tourist office before you go.
