Sé Catedral de Viseu
This massive stone structure with twin square bell towers anchors Cathedral Square, lending the plaza a dramatic air. Construction on this cathedral was started in the 13th century and continued off and on until the 18th century. Inside, massive Gothic pillars support a network of twisted, knotted forms that reach across the high, vaulted roof, and a dazzling, gilded, baroque high altar contrasts with the otherwise somber stone. The lines of the 18th-century upper level are harsh when compared with the graceful Italianate arches of the 16th-century lower level. To the right of the mannerist main portal is a double-tier cloister, which is connected to the cathedral by a well-preserved Gothic-style doorway. The cathedral's Sacred Art Museum has reliquaries from the 12th and 13th centuries. For great views of the cathedral, head a block south to the tiny square of Praça de Dom Duarte.
