Built to guard the southern gate of the Gradec town wall, the Lotrscak Tower (Kula Lotrscak) dates to the 13th century and has long been one of Zagreb's most recognizable landmarks.
Legend has it that this large, square Romanesque tower once held a bell that rang out each night prior to the closing of the gates to warn residents outside the walls to return (anyone left outside would have to remain there for the night).
