The Pskov Krom (or Pskov Kremlin) is an ancient citadel in Pskov. In the central part of the city, the Krom is located at the junction of the Velikaya River and smaller Pskova river. The citadel is of medieval origin, with the surrounding walls constructed starting in the late 1400s. The Krom was the administrative and spiritual centre of the Pskov Republic in the 15th century. In 2010, two of the towers of seven (the Vlasyevskaya, which dates to the 15th or 16th century, and the Rybnitskaya, which dates to 13th or 14th) were damaged in a fire.
References:The historical centre of Briançon is a strongly fortified town, built by Vauban to defend the region from Austrians in the 17th century. Its streets are very steep and narrow, though picturesque. Briançon lies at the foot of the descent from the Col de Montgenèvre, giving access to Turin, so a great number of other fortifications have been constructed on the surrounding heights, especially towards the east.
The Savoyards made two raids into French territory in 1691 and 1692. As a result, Vauban was dispatched to inspect the frontier defences, which had been ill-equiped to deal with the attack from Savoy. He returned to the area in 1700 to check on the progress that had been made since his first visit. When Vauban visited Briançon, work on the defences had already started under a local engineer, Monsieur d"Angrogne in 1692.
