Castle da Rocha Forte was built by Archbishop Juan Arias around 1240 and has since served as an archbishop's and cabildo's residence, witnessing much of the medieval history of Santiago. In the year 1255 appears the first documentary mention of the fortress in relation to the capitular constitutions of Juan Arias. The castle was situated in a strategic location by road from Padrón village to Santiago. Pilgrims followed that route from Portugal.
In addition to its purpose for defence, the castle was also a home for the Archbishop, which could provide the men of the local church a shelter from rioting citizens. In 1317, Berenguel de Landoira was nominated as Archbishop. The residents did not like him and started a rebellion. Archbishop Landoira had all the leaders of the rebellion executed. In the 15th century in Irmandiño wars the castle was damaged badly and it was abandoned. Later, in 1472 the walls were dismantled. During the Franco era the ruins were used as a hideout. In 1962, an electricity pylon was installed to the castle area.
Since 2001, a series of archaeological excavations have been carried out, thanks to an agreement between the City Council of Santiago and the University of Santiago de Compostela, in order to recover the deposit and consolidate it by means of the creation of an Archaeological Park.References:
The Amphitheatre of the Three Gauls was part of the federal sanctuary of the three Gauls dedicated to the cult of Rome and Augustus celebrated by the 60 Gallic tribes when they gathered at Lugdunum (Lyon). The amphitheatre was built at the foot of the La Croix-Rousse hill at what was then the confluence of the Rhône and Saône.
Excavations have revealed a basement of three elliptical walls linked by cross-walls and a channel surrounding the oval central arena. The arena was slightly sloped, with the building"s south part supported by a now-vanished vault. The arena"s dimensions are 67,6m by 42m. This phase of the amphitheatre housed games which accompanied the imperial cult, with its low capacity (1,800 seats) being enough for delegations from the 60 Gallic tribes.
The amphitheatre was expanded at the start of the 2nd century. Two galleries were added around the old amphitheatre, raising its width from 25 metres to 105 metres and its capacity to about 20,000 seats. In so doing it made it a building open to the whole population of Lugdunum and its environs.
