Mariánské náměstí is defined by four important buildings - the National Library, the Municipal Library in Prague, Prague City Hall, and the Clam-Gallas Palace. It primarily served as a parking lot throughout the 20th century. However, its fate is now slowly changing. The square has been in modified trial operation since 2019. Instead of parked cars, you now find Prague tables and chairs here. The end of 2020 also brought about something new. The city leadership approved the new appearance of the square designed by the XTOPIX architectural studio. The public space should serve as a place for meeting, rest and art.
