Ballywillan (Ballywillin) Church is situated one mile from Portrush on the Ballywillan Road. The name Ballywillin translates to ' town of the Mill' and was also known as Mylton. The church ruin you see today dates to around the 16th century and probably replaced or was renovated from an older church built on the site in the 14th century. This church, in turn, replaced the church of Portrush which existed approximately midway between Ramore headland and Crocknamac Street, there are no visible remains of this church which is known to have existed in the 12-13th century.
