A house that began as a seventeenth-century residence and has ended up as a convent carries a certain quiet layering of purpose, and Saint Wolstan's in County Kildare has accumulated more than its share of architectural identity shifts along the way. What visitors see today reads outwardly as an eighteenth-century country house, three storeys tall, five bays wide, with a gable-ended centre block and two-storey wings that overlap it on either side. The interior was remodelled again in the 1830s. The building has been altered so thoroughly across the centuries that its early origins are easy to overlook entirely.

Those origins are worth pausing on. According to Mark Bence-Jones, writing in 1978, the house originally belonged to the Alen family and was said to have been built in the early seventeenth century by John Allen, the same man credited with designing Jigginstown House near Naas. Jigginstown was the ambitious, never-completed palace commissioned by Thomas Wentworth, Earl of Strafford, the Lord Deputy of Ireland under Charles I, and it remains one of the most intriguing architectural fragments of that period, a vast unfinished brick structure that gives some sense of the scale Allen was working at. That the same architect may have produced Saint Wolstan's, in a much more domestic register, adds a thread of connection between a grand state project and a family house that has otherwise receded into ordinariness through successive remodelings.
