The parish church of St. Euphemia dominates Rovinj from the highest point of the old town peninsula. Built in Baroque style in 1736 on the site of a much earlier church, it is the most prominent landmark on this stretch of the Istrian coast — the 60-metre bell tower is visible for miles out to sea and serves as a navigational reference for fishing boats. The copper statue of St. Euphemia on the top of the tower rotates with the wind.
The interior is spacious and relatively plain, with an altarpiece of St. Euphemia by Valentin Metzinger. The highlight is the Roman sarcophagus believed to contain the saint's remains, displayed in a side chapel. Climbing the bell tower (when open) rewards you with sweeping views over the old town rooftops, the harbour, and the Adriatic. The church is usually open during the day; the tower has restricted hours.
