Adjoining New Town is Prague’s highly touristy, but also very interesting, Old Town (Staré Město). At the border between the two is the ancient Powder Tower, built in 1475 and long a part of the coronation route of Czech kings, which wound from Vyšehrad, through this tower, past the Town Hall in Old Town Square, across the Charles Bridge, through Mala Strana, and finally up the hill to Prague Castle.
