Městská knihovna v Praze, Public library in Old Town, Czech Republic

The Municipal Library of Prague is a neo-classical building on Mariánské Square, constructed in 1924–1929 to František Roith's design. Its four wings enclose a roofed courtyard holding a large hall with the lending library. The three-storey south wing facing the square has 19 window axes, a travertine facade and a five-axis portico with six allegorical figures by Ladislav Kofránek.

The Prague Municipal Library opened on 1 July 1891 as the Public Municipal Library of the Royal Capital City of Prague. After premises on Zderaz and at Spálená street, it moved in 1903 to a corner of Mariánské náměstí, where it was given notice four months later because of the Old Town clearance. In 1923 the Prague Municipal Insurance Company decided to donate a new building; František Roith won the 1925 competition, construction ran from May 1925, and the building was handed over on 25 October 1928.

The library functions as a gathering space where locals encounter literature and art through regular readings, concerts, and exhibitions that shape the cultural life of the neighborhood. These events create moments of connection between residents and creative expression.

The library is open Monday afternoons through Saturday and provides free WiFi and computer workstations for visitors. The facilities are easily accessible and allow for extended work sessions throughout the day.

The Idiom in the vestibule, nicknamed the "column of knowledge", was installed in 1998. Slovak artist Matej Krén built it from 8,000 books, and mirrors inside create the illusion of endless space. It stands in the entrance hall of the library's central building on Mariánské náměstí.
