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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
