Vanesa is a very active spanish postcrosser in the portuguese community of the Postcrossing forum. Two months ago she sent me this card of the Sabroso Castle.
Sobroso Castle is a 9th century medieval castle in the village of Vilasobroso in Galicia, Spain.
The castle is located in Vilasobroso, a village in the municipality of Mondariz, belonging to the comarca of O Condado. It sits on Landín Hill, overlooking the Condado valley, right up to the Portuguese border. Due to its strategic position, the castle was known as "the key of the Kingdom of Galicia".
The castle currently houses a cultural and ethnographic museum. - in: wikipedia
