Newark Castle is a late 15th or early 16th century stone tower house, founded by Kennedy of Bargany. Of four storeys and a garret, with a square gabled caphouse and a corbelled-out parapet with open rounds on the angles. Standing on a small craig, the first floor hall is above a vaulted basement and there is a western 17th century addition of one more storey but no parapet. With extensive mid 19th century, north, east and west additions, the tower was once encased by a moat and the east wing was demolished in 1977. 2 miles north-west is Greenan Castle and 4 miles west is Dunduff Castle.
