Ostroh Castle

Ostroh was first mentioned in 1100 in the Hypatian Codex as a fortress of Volynian princes. It was part of the Principality of Galicia–Volhynia from 1199.

In the mid 14th century the town became the residence of the Ostrozki princes – a family that has given Ukraine its famous warriors and commanders, Maecenases and enlighteners, builders and Orthodox Church patrons. A renowned representative of the family is Vasyl-Kostyantyn Ostrozki (1526–1608). He initiated the establishment of the Ostroh Slavic-Greek-Latin Academy, which was Eastern Europe's first higher education institution. In Ostroh, famous printer Ivan Fyodorov published the first Church Slavonic Bible (1581).

Ostroh received the Magdeburg rights on July 29, 1528, from Sigismund I the Old – King of Poland and Grand Duke of Lithuania of the Jagiellonian dynasty.

In the late 16th c. the Ostroh population was 5,000. That means, only Lviv, Kyiv, Kamyanets-Podolsky and Bila Tserkva in Ukraine exceeded Ostroh in population. In the city were 16 craft guilds, and three fairs were held annually. The Ostrozki princes received numerous privileges from the state for their city, including the right to free trade at the Ostroh fairs.
