Lugo is the only city in the world to be completely encircled by intact Roman walls. The fortifications were built in the 3rd century to repel attacks by wild Celtic tribes that inhabited the region. The continuously round, 2,117 metre long wall reaches heights of 10 to 15 metres, and has 71 towers and 10 gates. To walk along the top of this UNESCO World Heritage site is a remarkable experience featuring spectacular views of both Lugo and surrounding hilly countryside. The city´s bridge over the Miño River dates back to Roman times too, but centuries of maintenance have lessened its Roman character.
Founded on the site of a small grove of trees, sources suggest that Lugo´s name comes from the Latin word Lucus, which means "sacred grove", or "sacred forest”. Besides the Roman walls, Lugo´s sights include its cathedral, dedicated to St. Froilán and built about 1129. The cathedral´s main façade and towers date from 1769 and the choir stalls inside were carved in 1624 by Francisco Mouro.
Also visit the Gothic-style Church of St. Francis, which presently houses the Museo Provincial and features exhibits of Galician art and 18th century architecture.
Other interesting sights include the Church of St. Dominic, the Palace of the arts, and the Town Hall, a large Baroque structure with a mid-18th century façade and clock tower dating back to the 16th century.
After the guided tour you have some free time to shop before returning by bus to La Coruña.
