It is thought that the remarkable lodge on Mount Pelier Hill was erected c. 1725. The game-rich lands in the foothills of the Dublin Mountains had come into the possession of William Conolly of Castletown House when he purchased Rathfarnham Castle in 1724, and this hilltop with its spectacular views must have seemed an ideal location for a hunting lodge. Because of its vaulted stone roof, the building is one of the best-preserved early eighteenth-century hunting lodges in Ireland, in spite of having been burnt down, robbed of all its decorative stone to build a later lodge downhill to the north, and suffering a bonfire of tar barrels on its roof to celebrate the arrival of Queen Victoria in 1849.
In its original condition it must have been most impressive. In the centre of a well-proportioned Palladian façade a flight of cut-stone steps led up to the fan-lit entrance door on the first floor, which opened into a porch flanked by wall niches. Off the inner stair hall were the two main reception rooms, each with fireplaces and two tall windows looking out over that expansive view of the city and the bay. The number and distribution of wall niches in the reception rooms suggest that the original interior finishes were more than utilitarian. Over one of these rooms there was a third storey, probably a bedroom, while on the ground floor were the kitchen and servants’ quarters. Another room, possibly a bedroom, occupied a return at the rear: at ground-floor level beneath this is a room that may have been a wine cellar. At either end of the house, under lean-to roofs, there were stables, possibly one for horses and one for hounds, and outside one of them a stone mounting-block survives.
