Sant Martí d'Empúries's Parish Church is located in the old town area, facing the main square, and was built above the ruins of a mediaeval castle moat.
It is a late-Gothic temple whose building began in 1507 (as carved on one of the stones on its facade) and was completed circa 1538. It consists of a single nave, with a rosette window on its façade and a pointed-arched main gate with rather worn carvings. It is likely there had been a Romanesque church on this same spot, although records are uncertain.
Above the main gate, there are 3 commemorative tomb stones circa 10th, 13th and 16th centuries corresponding to various works made at the former and present new churches. Numerous fragments of Greco-Roman pottery intersperse the church stone walls. Inside, outstanding features are some carved bosses, several Paleo-Christian consecrated altar stones, and a Romanesque font. It is a protected Local Interest Cultural Asset .
