The Church of Ireland church at Glaslough is an example of an estate church set well within the scenically landscaped grounds of a seventeenth-century Plantation house and demesne, which has been owned by the Leslie family since 1665. Its form and detailing are fitting for its setting within the demesne of Castle Leslie and its construction history recalls the early history of the demesne and of later phases of remodelling by the Leslies, mirroring the history of the country house itself. The war memorial to the front of the church, and the pleasant setting within a stone boundary wall set off and contextualise the building. Its well built masonry, and carved and inscribed plaques enhance the structure, as do the slate-hangings and stained-glass windows. The exceptionally tall five-stage seventeenth-century tower, likely heightened in the eighteenth century and given buttresses in the nineteenth century, is an impressive structure that serves as a landmark in its lakeside setting. The apsidal interior is a very fine composition in sandstone. The various marble and brass plaques add historical and familial context to the church.
