The Monasterio de Santa María de El Paular is a former Carthusian monastery. Construction is believed to have begun in 1390 by orders of Henry II of Castile, and construction proceeded for fifty years under his son, John I of Castile. It was sited where an old chapel stood. Supposedly he was spurred to this project due to his plundering of a chartreuse during a campaign in France. This was the first chartreuse in Castille and Leon. In 1403, a small adjacent palace was built under Rodrigo Alonso. Multiple architects contributed to the complex, including Juan Guas, Rodrigo Gil de Hontañón, Francisco Hurtado and Vicente Acero. The refectory was designed in a Moorish style.
The monastery was dissolved in 1835, and not till 1876 was some state protection afforded to the site. Since 1954, part of the monastery is occupied by the Benedictine order; while part was a private luxury hotel, operating as the Sheraton Santa Maria de El Paular, for many years, until it closed in 2014.
The spectacular late-Baroque decorations of the chapel of the sacristy and its Transparente (mid-18th century) by Francisco Hurtado Izquierdo and containing polychromatic marbles, solomonic columns, and gilded leafwork, contrast with the rocky serene simpleness of the cloisters. The silver decoration of the church included a silver “custodia” weighing some 24 arrobas (approximately 15 kilogram per arroba), which among with many other items, was probably looted by Napoleon's troops. There is a large 15th century carved wood reredos in excellent condition, and a fine ironwork screen segregating the monastic choir from the nave.
While it still has an interesting library, its once famous collection of books and maps has been dispersed. In 1755, an earthquake damaged the tower and nave roof. Missing from the site are 52 paintings by Vincenzo Carducci on the life of St. Bruno and other devotional incidents. The paintings are in local museums, including the Prado in Madrid. The paintings were returned to the monastery after restoration in 2011.
Parts of both monastery and hotel are open for visits by the public.
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.
