McCarthy’s Castle, the Long House, Dolly Mount, Montpelier House, or as I tend to call it, Carthy’s Castle, was never a Castle or ever belonged to anyone named Carthy or McCarthy that anyone knows of. Then again, The Hellfire Club charges no membership fees, isn’t actually Hell, and is rarely on fire these days, so names aren’t always descriptions. It was built as a Hunting Lodge in the 18th Century by Henry Loftus, Earl of Ely, and owner of nearby Rathfarnham Castle among other things, and it was indeed very long, guarded each end by one of these three-story towers made to look like a castle.
The House interiors boasted some of the finest materials and design available contemporaneously, including intricate stuccoed ceilings and marble fireplaces. Similar to its nearest neighbour, the Hellfire Club, the owners didn’t stay too long in Dolly Mount, as they called it, after their niece Dolly Monroe, and a few years after it was built they vacated it for the final time, leaving it to gently slump into its ruinous decay.

Circular space in the chimney.
Looks like someone built a nest in it.
This too looks like the remains of an old nest.
