The cathedral of Evora is unique of its era, as most Romanesque-styled buildings have a clear line of symmetry running the length of the building. The Sé is markedly different by having two asymmetric towers: one tower finishing with a blue tiled coned spire, while the other is a fortified clock and bell tower. The Sé Cathedral name is derived from the two letters S and E, which in Latin stands for Sedes Episcopalis (the seat of the bishop); therefore, the Sé de Evora is the Bishop’s seat in Evora. The most historically important event that occurred in the Sé was the blessing of Vasco da Gama’s fleet's flags before his famous expedition to India.
