The tradition of the Iron Log (Stock im Eisen) comes from German-speaking countries. The main idea is that when a tradesman's apprentice arrives at the city on his guildsman's journey, he strikes a nail into the city's iron log. The Győr Log, however, has a bit of a different story: when Mátyás Zittrisch opened his spice shop and delicatessen named 'To the iron log' in the middle of the 19th century, he had an appropriate trade sign made with nails from a factory.

Built in the 17th century, the Vastuskós (Iron Log) House is home to the art history collection of the journalist Imre Patkó (1922-1983). The building houses the works of contemporary artists, Lajos Kassák, Endre Bálint, Victor Vasarely and Béla Kondor among others, as well as East Asian, African, and Oceanian ethnographic objects. The building was named after the iron log located at one of its corners, which according to the legend, each traveling craftsman who stayed in Győr struck a nail into to commemorate their visit.

Győr's renovated Baroque main square is an important site in the life of the city. This is where the Mary Column, the Benedictine Complex, the Apatúr House and the Iron Log Trade Sign, among others, is located.
