This national monument is the Neolithic Seefin Passage Tomb built around 5000 years ago on a 650m high mountain in North Wicklow. It’s name in Irish (Suidh Fhionn) means “The Seat of Fionn” and these tombs appear in ancient stories as entrances to the ‘otherworld’, ‘the homes of the gods’or symbolised the belly of a pregnant woman where the passage is the birth passage and the chamber is the womb. This incredible feat of engineering is made from thousands of tonnes of local rocks and stones and measures 25m in diameter and up to 4 metres high. This is only one of what appears to be a series of tombs built at a similar altitude in this beautiful region. Nearby are the Seefingan and Seahan Passage Tombs which also have similar large cairns of stones. Many of these tombs command some some of the most spectacular views in Ireland. It is believed that the original builders chose these locations so that they could claim ownership of all they could see and by placing their ancestors far above the low lying lands of the living, could watch over them from their tombs. The tomb was excavated by R.A. Macalister in 1931 however no artifacts or human remains were found. These may have been removed to other locations or were desecrated by tomb raiders over the millenia. The tomb has a passageway around 10m long and opens into a chamber with five compartments. According to Macalister there are two decorated stones at the entrance with faint megalithic artwork on them.
