The Belltower of the Church of Our Lady of Zvonik () is a disused Roman Catholic church in Split, Croatia. Built into a small space (an early guardhouse) within the ancient Iron Gate of Diocletian's western wall. Today little survives of the building, apart from the belltower, one of the oldest in Croatia. Read more on Wikipedia
