Starokostiantyniv, Ukraine with Ukrainian flag T-Shirt

Starokostiantyniv (Ukrainian: Старокостянтинів) is a city in the Khmelnytskyi Oblast (province) of western Ukraine. Serving as the administrative centre of the Starokostiantynivsky Raion (district), the city itself is also designated as a separate raion within the oblast. The city has a population of 34,700. Starokostyantyniv was founded in the 16th century when Kostiantyn Ostroz'skyi (1460–1530), built a fortress at the village of Kolishchentsi. The surviving Starokostiantyniv Castle was constructed by his son between 1561 and 1571. The village grew into a town which became known as "Old Constantine's Town" (Kostiantyniv Staryi) to prevent confusion with "New Constantine's Town" in the vicinity. 1648 saw the Battle of Starokostiantyniv.
