Ciudad Rodrigo () is a small cathedral city in the province of Salamanca, in western Spain, with a population in 2016 of 12,896. It is also the seat of a judicial district. The site of Ciudad Rodrigo, perched atop a rocky rise on the right bank of the River Águeda, has been occupied since the Neolithic Age. Known also as Mirobriga by those who wish to associate the city with an ancient Celtic village in the outskirts of the modern city. A key border fortress, it was the site of a 10-day siege by the Duke of Wellington. Geography Ciudad Rodrigo is situated on the right bank of the Águeda river, about south-west of Salamanca and away from the Portuguese border. The autovia A-62 (dual carriageway) links Ciudad Rodrigo with Salamanca, Valladolid and Burgos, and with Portugal. Climate At an elevation of Ciudad Rodrigo has an inland Mediterranean climate (Köppen: Csb) characterised by cool, damp winters and warm, dry summers with relatively cool nights during the summer. History Origins Ciudad Rodrigo was originally a Celtic village under the name of Mirobriga. The town was later taken by the Romans during the conquest of Lusitania and named Augustobriga. In the 12th century, the site was repopulated by King Ferdinand II of León, walling it and re-establishing the old Visigothic diocese of Calabria into the new bishopric as suffragan of the Diocese of Santiago de Compostela; it comprised a big part of the province of Salamanca, and a portion of the province of Cáceres, an act confirmed by Pope Alexander III in 1175. This led to the construction of the city's cathedral, an architectural hybrid of the Gothic and late Romanesque styles. King Alfonso VIII gave the city of Calabria to the Diocese of Ciudad Rodrigo in 1191. The first bishop of whom anything certain is known was called Pedro (1165) and one of the most celebrated was the learned jurist Don Diego de Covarruvias y Leyva (1560). Artistic works During the 15th century, a series of artworks of perhaps 35-panels (only 26 panels survive), known as the Retablo (altarpiece) of the Cathedral of the Ciudad Rodrigo was created by Fernando Gallego, Maestro Bartolomé, and the artists of their workshops. Over the centuries, the works became badly deteriorated. In 1954, they were acquired by the Samuel H. Kress Foundation which had them fully restored. In 1961, the foundation donated the works to
