The earliest historical proof of existence of the Hervartov village is from the year 1340. The exact date when the wooden church was built is not known. According to the saved remains of the original Gothic altar, which was probably in place in the second half of the 15th century - the altars of St. Catherine, Virgin Mary and St. Barbara are from the years 1460-1480. This assumption is supported by the fact that the architecture and overall conception of the interior of Hervartov's wooden church, such as its stencilled geometric painting in the presbytery, may be associated to some extent with several churches on the Polish side of the Carpathian Mountains.
Saint Francis Church has a Gothic character as represented by its tall but narrow structure unusual for a wooden church. The floor is made of stones again unlike in most of wooden churches where it is usually made of wood.
Hervartov church is part of the UNESCO World Heritage Site of Wooden churches of the Slovak Carpathians.
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.
