Betanzos

Betanzos () is a municipality in the autonomous community of Galicia in northwestern Spain in the province of A Coruña. It belongs to the comarca of Betanzos. In Roman times Betanzos was called Flauvium Brigantium or "Brigantium". During the Medieval period the settlement was known as "Carunio". 
The town is located in a fertile valley close to the Atlantic Ocean, and it has one of the best preserved old quarters in Galicia. Noteworthy is the Igrexa de San Francisco (St Francis Church), erected in 1387 by order of count Fernán Pérez de Andrade, whose tomb, decorated with hunting scenes, is inside of the church. The Igrexa de Santiago (St James Church), built in the 15th century by the guild of tailors, has a main portal decorated with a horseback statue of Saint James. The town is on the English Way path of the Camino de Santiago. 
Other sights in the town are several town palaces, a 16th-century clock tower, and the town walls, which preserve three of their original four gates.
There are two celebrations in Betanzos in August each year. At the festival of San Roque, a very large paper balloon is launched. Later in August, decorated boats sail along the Mandeo river to the nearby Os Caneiros.
