A cobbled street leads from behind the Venetian House to Piran's hilltop cathedral, baptistery and bell tower. The cathedral was built in baroque style in the early 17th century, on the site of an earlier church from 1344.
The cathedral's doors are usually open and a metal grille allows you to see some of the richly ornate and newly restored interior, but full access is via the Parish Museum of St George, which includes the church's treasury and catacombs.
Items of interest include a silver-plated St George slaying a dragon, and a wooden model of the church dating from 1595.
The highlight of the cathedral interior (not visible from the grille) is the remarkable, early-14th-century wooden sculpture, The Crucified from Piran, depicting Christ on the cross.
