Lotrscak Tower is a medieval tower in Zagreb's Upper Town, famous for its daily tradition: the Gric Cannon fires every day at exactly noon. This tradition, continuing for over 100 years, was originally to synchronize church bells across the city. Visitors can climb the steep narrow stairs to the observation platform at the top for a 360-degree panoramic view of Zagreb. The tower also houses small art exhibitions on the first and second floors and a gift shop with souvenirs, books, and jewelry on the ground floor
