Swedish conquerors established a sea fortress named Rågövik (“Rye Island Bay”) to the deep and wind-sheltered Paldiski Bay in the 17th century. Later it became a Russian naval base in the 18th century. Peter the Great planned to build a giant military port of there. The plan envisaged that the mole would offer shelter for the entire vast navy of Russia. Construction of the military port started in 1716. Despite the efforts of thousands of convicts, the planned 2-km-long giant facility could not be completed and even the completed part was quite soon destroyed by autumn storms.
In 1762, the Russians (Catherine II) renamed the sea fortress of Rogerwiek into Baltiyskiy Port (Baltic Port), and the Estonian pronounciation, Paldiski, became the official name in 1933. In 1962, Paldiski became a Soviet Navy nuclear submarine training centre. With two land-based nuclear reactors, and employing some 16,000 people, it was the largest such facility in the Soviet Union. Because of its importance, the whole city was closed off with barbed wire until the last Russian warship left in August 1994. Russia finally relinquished control of the nuclear reactor facilities in September 1995.

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.
