Oristano’s Cathedral is bigger and grander than you might expect from a city its size, and creates quite an impression as you emerge from the narrow, winding streets into the sun-drenched piazza Duomo and see it for the first time. The first documented mention of the church was in 1131. Much of it was rebuilt during the 14th century, though the only notable remaining elements of this are the transept chapels and the impressive bell tower. The rest of the Cathedral’s outside structure shows a typically 18th century Piedmontese style, which is mirrored by the elegant decor within.
