At no. 4 on Széchenyi Tér is a curious early Baroque house from the 17th century.

On one corner there’s a tree trunk studded with nails, the explanation being that every tradesman passing by the stump had to hammer a nail in for good luck.

Above it there’s a circular bay window, held up by sculpted corbels.

The house is a museum hosting the Imre Patkó Collection, notable for avant-garde art by the likes of Victor Vasarely, Béla Kondor, Endre Bálint and Lajos Kassák.
