Saranta Kolones ('Forty Columns castle') is a ruined medieval fortress inside the Paphos Archaeological Park. It takes its name from the large number of granite columns that were found on the site and probably once formed part of the ancient agora. The Byzantine castle is believed to have been built at the end of the 7th century AD to protect the port and the city of Nea Pafos from Arab raids. It was later remodeled by the Lusignans in the early 1200s.
The fortress had a three-metre thick wall with four huge corner towers and another four intermediary towers along the joining walls and moat surrounding the castle. Access was across a wooden bridge spanning the moat. The square courtyard measured 35 metres long by 35 metres wide, with a tower at each corner. The main entrance was through a fifth, horseshoe-shaped tower on the east side. Destroyed by an earthquake in 1222, the castle was subsequently abandoned.
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.
