Korela Fortress, at the town of Priozersk, was founded by the Karelians who named the place Käkisalmi. It was first mentioned in a Novgorodian chronicle of 1143 as Korela. Indeed, archeological digs have revealed a layer belonging to the 12th century. Swedish chronicles first reported of the settlement of Keksholm in 1294. Until the 16th century, the fortress belonged to the Novgorod Republic, followed by Muscovy. Novgorodians built the current stone bastions and towers in 1364 after a fire had destroyed the original wooden fortress in 1360.
During a Swedish-Novgorodian war in 1314, a small Karelian force conquered the fortress from the representatives of Novgorod. They invited Swedes to keep it against Novgorod. However, the Novgorodians managed to reconquer the fortress. The fortress was confirmed as belonging to Novgorod in the treaty of Nöteborg of 1323.
In the 1330s, the Novgorod Republic gave the castle of Korela (and practically the entire Votian fifth, including the forts of Oreshek and Ladoga) to duke Narimantas of Lithuania. In 1383 Korela, Oreshek and Koporye were inherited by Narimantas' son and heir, Patrikas, the forefather of the Galitzine princely clan. Next year the local burghers lodged a complaint about his administration. Patrikas was forced to exchange Korela for Ladoga and Russa. Patrikas occupied his lands in Ingria and Karelia at least from 1383 to 1397. In the year 1408, it is recorded that he settled in Moscow under the protection of Vasili I, together with his younger sons, Georgi and Fyodor, who had grown up in Ingria.
Soon after their seizure of Korela in 1580, the Swedes rebuilt the fortress following a Western European pattern of bastion fortifications. In the Treaty of Teusina of 1595 Sweden however undertook to return Korela to Russia. This was effectuated in 1597. During the subsequent Ingrian War starting 1610, Gustavus Adolphus reinforced Swedish control of the castle and the whole area. During the Time of Troubles, Korela was a prize promised by Vasily IV of Russia to Jacob De la Gardie as part of the Swedish De la Gardie Campaign to assist Russia against the Polish-Lithuanian commonwealth. They were incorporated with Sweden as Kexholms län in the peace of Stolbova in 1617. The fortress and the region remained with Sweden until Peter the Great captured the fortress during the Great Northern War.
In the mid-18th century, the fortress was turned into a political prison of Imperial Russia. Some participants of the Decembrist Revolt (1825) were confined there.References:
Soave castle was built in 934 to protect the area against the Hungarian invasions. It was remodelled by Cansignorio of the Scaliger family in the mid-1300s. in 1365 Cansignorio had the town walls erected and the Town hall was built in the same year.
The castle underwent various vicissitudes until, having lost its strategic importance, it was sold on the private market in 1596. In 1830 it was inherited by Giulio Camuzzoni who restored the manor and in particular the surroundings walls (with is twenty-four towers), the battlements and living-quarters.
Soave castle is a typical medieval military edifice, commanding the neighbourhood of the city from the Tenda Hill. It comprises a mastio (donjon) and three lines of walls forming three courts of different size. The outer line, with a gate and a draw bridge, is the most recent, built by the Venetians in the 15th century. It houses the remains of a small church from the 10th century.
The second and larger court, the first of the original castle, is called della Madonna for a fresco portraying St. Mary (1321). Another fresco is visible after the door leading to the inner court, and portrays a Scaliger soldier. The mastio is the most impressive feature of the castle. Bones found within showed it was used also as prison and place of torture.
The House called del Capitano (the Scaliger commander) houses Roman coins, weapons parts, medals and other ancient remains found during the most recent restoration. Adjacent is a bedroom with a 13th-century fresco with St. Mary and Madeleine and a dining room with medieval kitchenware. Another room houses the portraits of the most famous Scaliger figures: Mastino I, Cangrande, Cansignorio and Taddea da Carrara, wife of Mastino II; the portrait of Dante Alighieri testify an alleged sojourn of the poet in the castle.
