Every day, for over hundred and ten years, the cannon fires from the top of tower Lotrščak exactly at noon in memory of an event from Zagreb history. According to the legend, exactly at noon, the Grič canon fired a discharge from Lotrščak to the Turkish camp located across Sava and blew out a rooster (or a turkey) which the cook was taking to Pasha on a platter. After this event, the Turks scattered and did not attack Zagreb.
Once the main city fort, it is now one of Zagreb’s trademarks. This is the best preserved building within the city’s defensive system, its belvedere providing a wonderful view of Zagreb and its immediate surroundings. The fort was erected in mid-18th century and was named Lotrščak for the bell within it, the "campana latrunculorum" or "the bell of thieves", which rang every night before the town gates closed.
