On a rise to the north-west of the main house at Waterstown, County Westmeath can be seen one of the former estate’s most distinctive features: a mid-18th century dovecote: like other buildings on the site, its design has traditionally been attributed to Richard Castle and, once again, the building features a decidedly eccentric use of classical motifs. On top of a square base rises an octagonal tower, each with a blind window. The tower is in turn topped by a spire concluding in a delicate weather vane. Near the summit of the spire are a series of square openings with landing ledges: the only overt evidence of the dovecote’s function.

Holding a great vaulted chamber, the square base was originally open to the elements: about two-thirds up each side a key-stoned arch sprung from the projecting string-course. However, at some later date, most of the openings were filled with rubble stone, and smaller windows inserted on three sides: a large fireplace was created on the fourth. Presumably the intention was to convert the space into a summer or tea house. Alas, like everything else at Waterstown, the building’s present condition is perilous.
