Oster is a small town on the left bank of the Desna River, where the Oster River flows into it, serving as the center of the Oster hromada in Chernihiv Raion. About 5.5 thousand people live here. It is one of the oldest towns on the Left Bank, and its main landmark is the ruins of Yurii's Bozhnytsia, a church from the 11th–12th centuries.
Horodets on the Oster
The town was first mentioned in chronicles in 1098 as "Horodets on the Vostr", or Yurii's Town. It was founded by Kyiv Prince Volodymyr Monomakh. Horodets stood at the crossroads of trade routes from the northern principalities to Kyiv and Byzantium, so it developed rapidly — and suffered just as frequently from wars. At the beginning of the 14th century, a new settlement grew closer to the Desna, which was named Oster.
Yurii's Bozhnytsia
The Church of St. Michael was built in 1098 by order of Monomakh as a temple of the princely castle. In the 12th century, Oster belonged to Yurii Dolgorukiy, and the prince decorated his court church with frescoes similar to the murals of Saint Sophia of Kyiv — hence the name "Yurii's Bozhnytsia". In 1152, the church suffered when the town was burned by Prince Iziaslav Mstyslavych, in 1195 it was restored by Vsevolod Yuriyovych, and in 1240 it was destroyed by the Mongols.
In 1695 the church was restored, but in 1753 it was struck by lightning, and the hill began to slide toward the river. At the end of the 18th and the beginning of the 19th century, most of the building was dismantled; only the altar part — the apse and a fragment of the wall with 12th-century frescoes — survived. They were restored in 1907, and later in 1924, 1950, and 1977–1980. The bozhnytsia is part of the national heritage site "Horodyshche-Detynets of the Chronicle Town of Horodets-on-the-Oster".
From Starostvo to Povit
Under Lithuania, Oster was given to Prince Yurii Polovets-Rozhynovskyi, and a castle was built here in 1538. In the first half of the 17th century, the town was the center of the Oster starostvo, and later a sotnia town of the Kyiv Regiment. From 1764, Oster became a povit center. Up to a thousand barges and baidaks passed by the town on the Desna every year, so trade thrived here even in the 19th century. Oster has a local history museum.
Coat of Arms
The historical coat of arms of Oster features a town gate with three towers and a golden cross on a green field. The town received the privilege for the coat of arms and Magdeburg rights for its courage during the siege of 1663–1664.
How to Get There
Oster lies between Kyiv and Chernihiv, on the Desna River. The bozhnytsia stands at the entrance to the town from the south, on a high hill. Nearby is Kozelets with the Rozumovsky Cathedral.
