The Pitareti monastery consists of the Theotokos church, a belfry, the ruined wall and several smaller accessory buildings. The main church appears to have been built in the reign of George IV early in the 13th century. Its design conforms to the contemporary canon of a Georgian domed church and shares a series of common features – such as a typical cross-in-square plan and a single lateral porch – with the monasteries of Betania, Kvatakhevi, and Timotesubani. The façades are decorated, accentuating the niches and dormers. The entire interior was once frescoed, but only significantly damaged fragments of those murals survive.
The monastery was a property and a burial ground of the noble family of Kachibadze-Baratashvili and, since 1536, of their offshoots – the princes Orbelishvili. A 14th-century inscription mentions a ctitor – the royal chamberlain Kavtar Kachibadze. Another inscription, from a grave stone, records the name of Qaplan Orbelishvili who refurnished the monastery in 1671. The monastery thrived at Pitareti until 1752 when it was forced to close due to a marauding attack from Dagestan.
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.
