The Novosilka Castle () is a castle located in Novosilka, Ternopil Oblast, Ukraine. The castle was built by the knightly Kostjuków-Woà Âodyjowski family, to which the village Novosilka had belonged from 1547, and an architectural monument of local importance.
In 1672 the castle was destroyed during a Turkish invasion and was not later rebuilt. Its ruins survived until the mid-19th century, when they were demolished and the material was used to build a church, houses, and to pave the road.
It was a stone building surrounded by a wall and had four towers. To this day, what remains of it is a round, several-story tower known as Woà Âodyjowski's Tower from the 17th century and small, overgrown fragments of earthen fortifications.
