Prague 1, formally the Prague 1 Municipal District (Czech: Městská část Praha 1), is a second-tier municipality in Prague. It is co-extensive with the national administrative district (správní obvod) of the same name.
Prague 1 includes most of the medieval heart of the city. All of Staré Město (the Old Town) and Josefov (the Jewish Quarter) are in the district, as are most of Malá Strana (the Little Quarter), Hradčany and Nové Město (the New Town). Tiny parts of Holešovice and Vinohrady (the State Opera and new building of the National Museum) round out the district. The district has remained intact since its creation in 1960.
