Se Cathedral

The Sé de Lisboa, the Sé Cathedral or simply just the Sé, is a solemn-looking cathedral that reflects the Romanesque style of the 12th century. Built on the grounds of the city's main mosque, the cathedral was raised to celebrate the Moors' defeat in the mid-1100s. Although it didn't make the top of many recent visitors' itineraries, most do recommend stopping in if you were in the area -- it's just a quick walk from the Baixa-Chiada metro station. Open daily, the cathedral is free to explore; touring the cloister and sacristy costs a small fee.
