Château de Landreville was built in the early 13th century and remodelled in the middle of the 16th century. It is a rectangular 'maison forte' (strong house) flanked by four cylindrical towers with 'pepper-pot' roofs, surrounded by water-filled moats, with a six hectares park, stables and two pavilions.
It is a rare example of a still practically intact manorial residence of the pre-Renaissance Ardennes region.
In 800 years of history it has witnessed the lives of many families, including the Landrevilles, Grandprés, Chennerys, Beauvais, Maillarts, Meixmorons. The portrait of Claude François de Maillart, lord and marquis de Landreville, was painted by Nicolas de Largillière around 1735.
Construction of the current building dates from the middle of the 16th century, the date of 1567 being seen on one of the chimneys. The building plan is typical since the 15th century, with a rectangular home confined by four round towers. The moat remains visible on three sides.
On three floors, rectangular fire holes are let into the towers to provide protection for the four sides. They still have the support bars that made it possible to stabilise the weapon.
The main door is decorated with embossed designs and statuettes of caryatids, characteristic of the French Renaissance after 1550.
The lower stage is entirely vaulted in stone. In the kitchen, the vaulting is supported by a single pillar in the centre, as was usual. One of the towers contains a spiral staircase. The two floors each include French-style ceilings and chimneys. The two chimneys on the first floor were partly modified in the 19th century.
The buildings which surround the castle are all more recent. The manager's house carries the year 1773. A symmetrical building is an addition from the end of the 19th century. At that time, the buildings located at the south-western entry to the castle were destroyed. The castle is testimony to the military architecture of 16th-century Ardennes.
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.
