Due to its strategic position, the Sobroso castle was known as 'the key of the Kingdom of Galicia'. The name of the Castle, and the village itself, comes from the Latin SUBEROSUM, in reference to the 'sobreiras', Quercus suber or cork trees that once surrounded it.
The oldest reference to Sobroso Castle dates back to 1096. The castle that stands today dates back to the 14th or 15th century construction consisting of 2 enclosures. The outer one is irregular and the entrance is made through a drawbridge, and the inner one is rectangular with its keep on its weakest side.
In the 15th century, Sobroso Castle saw the fight between the Sarmientos and Pedro Madruga, but after that the castle wasn't much active.
The castle was restored from its ruinous state thanks to the efforts of local journalist Alejo Carrera Muñoz, who in 1923 bought the ruins of the castle from the Count of Torre Cedeira. He carried out the restoration work single-handedly, without any help from local authorities, until his death in 1967. In 1981, the neighbouring municipality of Ponteareas purchased the castle from Carrera's only child, Zita Teresa Carrera Ferreira, for 30 million pesetas. From 1995 onwards, the local council began their own restoration work on the castle.
The castle currently houses a cultural and ethnographic museum.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
