The Castle of Lindoso is a medieval castle in the civil parish of Lindoso, municipality of Ponte da Barca. Little is known of the early era. It is believed the fortress was started under the 13th century reign of Afonso III of Portugal, entered in strengthening efforts of the defensive system of borders, undertaken by that ruler.
During the time of the Restoration of Portuguese independence, the castle and its location gained importance in view of its border location. For this reason, the location was used as a support base in the context of Portuguese incursions in Galicia by the military forces of Portugal in September 1641. As the war progressed, the castle received modernization and restoration works, which were completed around 1666 (date inscribed on the lintel of a door). It was only three years after briefly falling into the hands of Spanish troops. It is believed that the works have been dragged for a few more decades, since 1720 to date of completion of the main ravelin that defends the main entrance.
The castle saw a defensive state in the Napoleonic Wars but never saw action. It has never been used since.Peacetime took its toll. Neglect and lack of maintenance saw the castle slowly wear away from the weather and elements. The Castle of Lindoso was declared a National Monument by the Portuguese Government in a decree on June 23, 1910.
The structure is constructed using stone masonry walls, the top of which is surrounded by a battlement. The north and south ends of the tower are accessible by doors opened by drawbridge.
The keep still stands, having been divided into two floors.References:
Varberg Fortress was built in 1287-1300 by count Jacob Nielsen as protection against his Danish king, who had declared him an outlaw after the murder of King Eric V of Denmark. Jacob had close connections with king Eric II of Norway and as a result got substantial Norwegian assistance with the construction. The fortress, as well as half the county, became Norwegian in 1305.
King Eric's grand daughter, Ingeborg Håkansdotter, inherited the area from her father, King Haakon V of Norway. She and her husband, Eric, Duke of Södermanland, established a semi-independent state out of their Norwegian, Swedish and Danish counties until the death of Erik. They spent considerable time at the fortress. Their son, King Magnus IV of Sweden (Magnus VII of Norway), spent much time at the fortress as well.
The fortress was augmented during the late 16th and early 17th century on order by King Christian IV of Denmark. However, after the Treaty of Brömsebro in 1645 the fortress became Swedish. It was used as a military installation until 1830 and as a prison from the end of the 17th Century until 1931.
It is currently used as a museum and bed and breakfast as well as private accommodation. The moat of the fortress is said to be inhabited by a small lake monster. In August 2006, a couple of witnesses claimed to have seen the monster emerge from the dark water and devour a duck. The creature is described as brown, hairless and with a 40 cm long tail.
