Sé Velha

Transept Dome, Coimbra, Portugal
Sé Velha, or the Old Cathedral, is a Romanesque church dating to the late 12th and early 13th centuries when Coimbra was still the capital of Portugal. Instead of a dome, a Romanesque lantern-tower surmounts the transept crossing. The tower windows are one of the main sources of natural light in the cathedral. Sé Velha is the only Portuguese cathedral built during the Reconquista era which has survived relatively intact.
