Built in Neo-Baroque style, this is a U-shaped, two-story building with monument status. This building is one of Győr's most renowned pieces of real estate, it is the city's symbol. From its tower, the folk song starting with the lyrics 'the wind blows off the old Danube' can be heard every hour and the bells chime at 11 AM and 5 PM. On October 25, 1956, the revolutionary crowd removed the red star from the building's facade and the Győr Council was formed here the next day.

One of the newest ornamental fountains in downtown Győr, the 365 kg soda siphon was created by glass-maker László Hefter of Győr. Apart from the discovery of the dynamo principle, Ányos Jedlik is also credited with the basics of carbonated water production. The fountain is a testament to this discovery.

In 1956, the crowd gathered around what is today the Trianon Memorial, they brought down what was then a huge Soviet heroes' monument.
