Old Parish Church, Ronaldshay Crescent, Grangemouth

The Old Parish Church on Ronaldshay Crescent in Grangemouth was established with its foundation stone laid in 1910. This large church features a cruciform plan and was built for the Established Church. It is correctly oriented with a single south aisle, transepts, and church halls to the east. The church showcases decorated tracery and has an asymmetrically placed square-plan entrance tower at the northwest. The tower has a tall lower stage with a pointed entrance portal to the north, adorned with square billet-moulding. The open belfry stage features pairs of tall, shallow-arched openings with trefoil cusped tracery on each elevation, topped with a shaped crenellated parapet and a crocketted pinnacle positioned asymmetrically over the northeast angle. The steep-pitched roof is covered with grey slate and red ridge tiles, sloping down low over the south aisle.

On the north elevation facing Ronaldshay Crescent, the entrance tower is located on the right, with two set-back nave windows at the center featuring curvilinear Decorated tracery. A slim transept gable projects to the left, and a deep chancel is set back behind a subsidiary single-storey entrance on the left. The west gable has two 2-light curvilinear windows at the upper level, separated by a central buttress and a canopied niche, with square-headed 2-light windows below. The east-facing windows of the church halls have been replaced in an unsympathetic manner with aluminium framed windows.

Inside, the church features timber pointed barrel roofs in the nave, chancel, and transepts, which join to create an elaborate groin vault in front of the pointed chancel arch, decorated with round billet moulding. The nave arcades are supported by polished ashlar octagonal shafts. The single south aisle has a mono-pitched roof with latticed cross-braces. The window tracery includes a Perpendicular/Decorated transitional tracery in the east chancel window, which contains stained glass; the transepts feature Flamboyant/Curvilinear tracery with clear leaded glass; and the three-light cusped windows in the south aisle also contain stained glass, complemented by detached arcaded screens in front and free-standing shafts rising from sloping cills.
