Built c 1864 this is one of the last and best of the classical Presbyterian churches of Ulster. A splendid tetrastyle Ionic pedimented stucco portico raised on a granite plinth. The interior is extremely fine. The U-shaped gallery is carried on unusual slim green-painted cast-iron Roman Ionic columns. The box pews are excellent.

There is a tall traditional pulpit with precentor’s box below, reached by double-curved flights of 13 stairs flanked by cast-iron balusters. The compartmented ceiling has an enormous feathered central rose. In the vestibule there are twin curling staircases to the gallery; the floor is of ancient granite slabs and there is a good memorial tablet to Hugh Dunbar by R Love of Belfast. The detailing of the church throughout is of the highest quality, the church being of particular merit.
