Town Hall building is actually The Library of Juraj Fándly in Trnava. This is referenced on the windows on the ground floor with "library" signs.
The Town Hall's sign on the building was edited in the postproduction. The original sign is Economic Bank, referencing the historic use of the building. This sign was found during the reconstruction in the 2016. At the time, The Library of Juraj Fándly in Trnava was longtime established institution in the building and decided to keep the sign.
