Debrecen's County Hall is an Art Nouveau building completed in 1911. It was designed by Zoltán Bálint and Lajos Jámbor, and its best-known interior feature is the stained glass in the banquet hall, made by Károly Kernstok.
The building is still an official institution, so access may be limited, but the exterior is worth noticing on an architecture walk through central Debrecen.
