Montpelier Hill

Montpelier Hill is a 383-meter (1257-foot) summit on the northern section of the ridge encircling Glenasmole valley in County Dublin. Stone ruins stand at the highest point and overlook gentle slopes and moorland in all directions.

William Conolly built a residence in 1725 that later served as the meeting place for a notorious club. Between 1735 and 1741, gatherings took place here that became known for their provocative atmosphere.

The name comes from a residence that once stood on the hill and whose stone walls remain visible today. Hikers often encounter the remains of a prehistoric passage tomb set into the rock, evidence of early settlement.

The hiking trails begin at the parking area along road R115 and lead through open moorland up to the summit. The ascent takes about one hour and follows partly rocky paths that can become slippery when wet.

Shortly after the residence was completed, a severe storm carried away the roof, an event still recounted today. Some visitors report unusual sounds in the ruins, especially on windy days.
