During the Plantation, English colonials built a fortified house in the village. It had surrounding walls and two circular towers at opposite corners. Recent excavations have revealed that the fortified house was built on the site of a former Gaelic ringfort. During the 1641 rebellion the house was attacked by Irish rebels, but it remained intact. Many other houses in the village were burnt to the ground. Locally it was called "The Castle" and is located on Castle Street. The refurbished house was opened to the public in 1996 as "Bellaghy Bawn". It is a museum featuring exhibitions on local history.
