The Kloosterkerk (or Cloister Church) was originally a monastery first built for the Dominicans in The Hague in 1397. A thriving new center of arts was established in The Hague by the Court of Albrecht of Bavaria (1336–1404) and his second wife Margaret of Cleves. Some known artistic products to have been produced in this period are an important illuminated manuscript, the Hours of Margaret of Cleves commissioned between 1395-1400, and the visually similar Biblia pauperum.
In 1420 a fire raged through the monastery, but serious renovations are not recorded until the church's southern transept was added in the beginning of the 16th century. The church was expanded around 1540 with an enlarged aisle and side chapels. The center barrel vaulted aisle is 20 meters high and 11.5 meters wide. The worship space became a pilgrimage church, where people could visit and pass through, while services were being held in the central aisle or nave. At this time the church was also dedicated to St. Vincent, a Valencian Dominican missionary who was canonized in 1455.
The church was stripped of Catholic decorations during the beeldenstorm (iconoclasm of 1566). A number of monks lived on for a few more years, but in 1574 the last few monks left. After being abandoned for 12 years, the church had deteriorated and some suggested to tear it down. In 1588 a cavalry company seeking shelter settled in the former church. The following year the church and choir were made into a cannon foundry for the States of Holland and West Friesland. The choir was used as a foundry and the church served as a munition store with the two walled off from each other. On November 3, 1690, the ammunition stored in the church exploded leaving only one wall of the monastery remaining. The monastery then temporarily served as a hospital. In 1583 most of the monastery was demolished, though the church remained.
A part of the building became a church again in 1617 after remonstrants had successfully 'squatted' it. In 1620 a mechanical clock was added to the tower, made by Huyck Hopcoper. For the centuries to follow the church was used for Dutch reformist worship with the pulpit standing against the north wall. Throughout the 17th century, the burial of people in the church brought money and numerous hatchments. Most walls and columns were covered with hatchments, with the graves predominantly in the choir.
Rosettes in the ceiling are attributed to Gerhard Jansen (1868–1956). Other furnishings include a pulpit of oak with Flemish carvings, circa 1700. Carvings on the pulpit show the Four Evangelists. Stained glass windows throughout the church are attributed to Lou Asperslagh (1893–1949). The first liturgical service of the Dutch Reformed Church was held in the Kloosterkerk in 1911 and an impending demolition avoided in 1912. For the next two years the dilapidated church building was restored. Subsequent improvements include restoration of furniture brought from the former Duinoord Kloosterkerk; and the wall between the nave and choir was removed. In 1966 an organ by Danish organ builder Marcussen was installed.
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.
