The Aughnacliffe Portal TombsContact Details
Portal Tombs are considered to be one of the earliest forms of megalithic construction, dating to over 5000 years ago. The Aughnacliff Dolmen, as it is known locally, is one of four such tombs in County Longford.
Along with the other major dolmen at nearby Cleenrath, the monument has a traditional connection with the ancient legend of Diarmuid and Grainne. It is believed to have been one of their resting places on their flight from the legendary Fionn Mac Cumhaill.
