The Sanctuary of Our Lady of Oro is a place of worship in the Zuia Valley of northern Spain. It is about 3.5 kilometres (2.2 mi) from Murgia, in the center of the valley. The first known document mentioning it dates to 1138.
Local archeologists conducted four excavations from 1964 to 1967, and found evidence of human habitation in three eras. The oldest dates to the late Bronze Age (850-700 BC). A later community inhabited the area from 450 to 350 BC, followed by settlement during the later Roman Empire.
Nothing remains of the original Romanesque church. According to some historians, the sanctuary dates from the late 11th century to the 12th century. This is evidenced by its Romanesque images, similar to those in churches in the nearby villages of Domaikia, Markina-Xemein and Gillerna. The main church vaults were apparently constructed from the end of the 14th to the 15th century, with false plaster vaults in the sacristy dating to 1771.
The church's Baroque altar, built by Antonio de Alvarado in 1691, was preserved after the 1964 renovation and the medieval statue of Our Lady of Oro was restored in 1930. There are two chapels, one dating to 1638 and the other to 1761.
References:Towering 52 meters above the sea, Bengtskär lighthouse is the tallest one in Scandinavia. The building started in in 1905 after the shipwreck of S/S Helsingfors and was completed in 1906. The lighthouse was designed by architect Florentin Granholm. On December a special petrol lantern, designed and built in Paris, was brought to Bengtskär and installed atop the tower.
German fleet bombarded Bengstkär in the First World War in 1914. Since the Gulf of Finland was heavily mined, it was not until 1919 that the surrounding seas were declared safe for shipping, that the light was lit again.
After the war the military value of Bengtskär increased as part of the defence system of independent Finland. In Second World War (1941) Soviet Union made a suprise attack to island. After a bloody battle, the small Finnish garrison emerged victorious. Intermittent repairs to the facility continued during the post-war period.
