Tui is an episcopal city, capital of one of the seven former provinces of the old Kingdom of Galicia. An exceptional example of a medieval city, it stands on a pronounced promontory crowned by the Cathedral, from which a complex maze of medieval streets lead to the Miño River. An ensemble of narrow porticoed streets swirl around the Romanesque-style Cathedral-Fortress, a building with pointed arches in which the cathedral and the diocesan museums are located. Some other cultural and tourist landmarks are the Encerradas Convent, built during the 17th and 18th centuries; the San Telmo Chapel, the only example of Baroque-Portuguese architecture in Galicia; the Santo Domingo Church, in the Gothic-style with impressive Baroque altarpieces; and the San Francisco Convent, built on the former episcopal palace grounds of La Oliveira in the 17th and 18th centuries. Regarding Tui’s wealth of monuments, the remains of a wall built in the 12th century for the defence of the city may be one of the most noteworthy. Tui was of great relevance during the Suebi and Visigothic periods, even becoming the residence of Monarchs, and now it has grown into one of the better preserved historic urban sites in Galicia, which cannot be missed.
