The construction of Paide order castle was started in 1265 under the leadership of Konrad von Mandern. The original tower of Tall Hermann was octagonal with the height of over 30 meters and the thickness of the walls of about 3 meters.
At the beginning of the Livonian War the Russians repeatedly besieged Paide, but only in 1573 they finally managed to invade Paide. After that it changed hands several times until the Swedes got it in 1608. In 1638 they removed Paide from the list of castles.
The rampart tower and castle ruins were first conserved at the end of 19th century. In 1913 a park was planted on the hill. In 1941 Soviet soldiers destroyed the rampart tower, the symbol of both Paide and Järva County. To celebrate the 650th anniversary of the St. George's Night uprising the tower was restored in 1993. Today it houses a museum.

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.
