Koporye contains some of the most impressive medieval ruins in Russia. The first wooden fortress on the coast of the Koporye Bay was built by the Teutonic Knights in 1240, only to be destroyed by Alexander Nevsky the next year. The second fortress was built in stone by Alexander's son Dmitry Alexandrovich in 1280. Enraged by the prince's independence, the Novgorodians razed the fortress two years later.
Meanwhile the Swedes took advantage of this and occupied the banks of the Narova river. The Novgorodians had to restore the stone fort in 1297. Koporye was the strongest stronghold in the region and survived numerous attacks during the Swedish-Novgorodian Wars.
After Novgorod's incorporation into Muscovy, the fortress was strengthened and rebuilt to withstand cannon fire. Most extant structures belong to that period. Russian forces surrendered Koporye during the Livonian War but regained it under the Treaty of Tyavzino.
During the Time of Troubles Koporye was attacked by 2,500 Swedes, ten times more than the defenders. The Russian garrison had to surrender, and Koporye remained Swedish until 1703, known as Koporje or Caporie/Capurien, constituting an important part of Swedish Ingria.
As the Gulf of Finland grew shallow and receded to the north, the site began to lose its maritime importance. In 1703, during the Great Northern War, a major Russian army under Boris Sheremetev regained Koporye, which was defended by 80 Swedish soldiers under the commandant, Captain Wasili Apolloff. Huge gaps in the walls from the disastrous fire of the Russian artillery may still be seen.
Despite some repairs undertaken in the 19th century, the fortress survives in a ruined state. Also ruined is the 15th century Church of the Transfiguration within the fortress.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
