Red Gap


Red Gap, also known as Saggart Hill or Slieve Thoul, is a hill 397 metres above sea level situated 16 kilometres southwest of Dublin city centre in the Dublin Mountains close to Saggart and Rathcoole. The hill gets its name from the townland of 'Redgap' which lies just to the north of it. Today, Red Gap is home to farmland and telecommunication masts. The hill has FM radio transmitters for Newstalk, Kfm, LMFM, iRadio and East Coast FM.
The hill is also home to low-power fill in transmitters of Nova 100 and 4FM, designed to cover the Dublin commuter belt
The old-time song "Campbell's farewell to Red Gap" is believed to be referring to this hill.

Archaeology

Rosaleen Dwyer, Heritage Officer of South [Dublin County Council], noted the presence of archaeological sites on the hill in a 2015 talk, explaining:

Another of the upland sites are over there towards Saggart Hill... Slieve Thoul wood and Lugg Wood, again you've got a concentration of prehistoric burial tombs including two passage tombs inside the hill itself, two further passage tombs on the lower slopes, a barrow in Lugg Woods itself, and three further barrows in an enclosure further south so that's a huge collection of archaeology that's just asking to be interpreted in the correct way with appropriate routes and trails..."
