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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
