Kremlin of Pereslavl-Zalessky, Medieval defensive fortress in Pereslavl-Zalessky, Russia.

The Kremlin of Pereslavl-Zalessky is a medieval fortress in this town in Russia. Its earthen ramparts encircle the center and enclose several churches and administrative buildings from different centuries.

Yuri Dolgoruky moved the fortress from Kleshchin to the mouth of the Trubezh in 1152, naming it after Pereyaslavl in the south. Its ramparts stretched over 2.5 km, and by 1194 Prince Vsevolod the Big Nest had the wooden walls rebuilt. It withstood sieges by the Tverians in 1304 and Lithuanians in 1372, but was sacked by the Mongols in 1238, 1252, 1282, 1293, 1382 and 1408. The wooden walls were dismantled in 1759.

Inside the ramparts stood the Red Square with the town market, alongside the white-stone Transfiguration Cathedral and a brick church of Metropolitan Peter, probably on the site of the 12th–14th-century princely court. In 1659 the Sretensky Novodevichy Monastery was founded within the kremlin; its Church of the Vladimir Icon and Church of Alexander Nevsky were built in 1740 with money from the merchant and manufacturer F. Ugrimov.

You can walk along the ramparts and enjoy views of the lake and countryside around you. The grounds are open to visitors and easy to explore on foot.

The ramparts rest on oak and aspen log frames laid in three courses and filled with earth, built in the 12th century. The 1691 inventory lists twelve towers, including three gate towers, and a secret passage from the Taynitskaya Tower to the Trubezh River for water supply.
