Built into a small space (an early guardhouse) within the ancient Golden Gate of Diocletian's northern wall.[2][3] One of the oldest churchs in the city, Today St. Martin's Church is one of Split's tourist attractions (one of only two closest churches in the city) and known for its fine 11th centery chancel screen. It is currently in the care of the Dominican sisters, who have a monastery next door, and is open to the public to visit.
