Gori Castle is a medieval citadel in Georgia, standing above the city of Gori on a rocky hill. The castle first appears in the 13th century records but archaeological evidence shows that the area had already been fortified in the last centuries BC. The fortress controlled major strategic and economic routes and accommodated a large garrison. In the 16th century the Ottomans captured it to overawe Tbilisi. In 1598 the Georgians besieged it to no avail; in 1599 they feigned a relaxation of the siege for Lent before launching a surprise attack at night to regain the citadel. The fortress continued to change hands between the Georgians and the Persians in the 17th century.
The citadel acquired the present-day form under the Georgian kings Rostom of Kartli in the 1630s and Erekle II in 1774. After the Russian annexation of Georgia in 1801, the fortress was garrisoned by a Russian grenadier battalion, but its importance gradually declined and the fortifications went defunct.
Gori Fortress was significantly damaged by the earthquake in 1920. The best preserved structure is Tskhra-kara ('the Nine-gated'), which looks to the west, and is adjoined by the supplementary walls on the south and east.
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.
