The church sits at the hilltop and is visible from virtually every point in Piran – its massive silhouette with the bell tower dominates the tile rooftops below. The Renaissance façade (1608) follows models by Andrea Palladio. Inside – seven altars, a painted wooden ceiling, paintings from the Venetian school, and an early Gothic wooden "Crucifix of Piran" from the 14th century. The main altar (1788, Gasparo Albertini) features a painting of the Madonna with Child, Saints George, Nicholas, and Mark. Baroque marble side altars were crafted by Venetian masters including Bonfante Torre and the Gropelli brothers.
The freestanding bell tower is the main draw for visitors. 146 wooden steps along a narrow spiral staircase lead to a viewing platform at about 46 m height. At the top – four bells (the oldest from the 15th century) and a 3.6 m weathervane depicting the Archangel Michael. From the platform – a 360° panorama: Piran's tile rooftops and the Adriatic to the west, the Italian coastline toward Trieste to the north, Croatia to the south. On clear days, the Julian Alps are visible on the horizon.
In front of the church entrance is a broad lawn, once a cemetery. From here you get an open view over the Bay of Trieste, Tartini Square, and neighboring coastal settlements. Nearby – the octagonal Baptistery of St. John the Baptist (1650), which uses a 1st-century Roman tombstone as its baptismal font.
