It has slipped towards the back and rests on one of the eastern supporting stones and on the ground.

Portal tombs are megalithic structures of the British Isles in which two upright stones of equal height, with a door stone between them, form the front of a chamber covered by a capstone that is sometimes enormous.
At Garran there are two portal stones about 1.5 m high, of which the right-hand one is split. Two side stones on each side and one end stone survive, all in situ. The capstone is about 2.4 m long and 1.0 m thick. It has slipped towards the back and rests on one of the eastern supporting stones and on the ground. The door stone is missing. The chamber measures about 2.0 × 1.0 m and opens to the north-west.

In the Irish classification of megalithic tombs set out by Seán Ó Nualláin and Rúaidhrí de Valera in 1961, portal dolmens are one of four categories, alongside court cairns, wedge-shaped gallery graves and passage tombs. Most portal tombs in Ireland date from the Neolithic, between 4000 and 3000 BCE, and some were covered by a mound of earth or smaller stones that has since eroded away.
Tradition and region
About this kind of monument
Portal tombs
A portal tomb, or portal dolmen, is the Irish and British version of the dolmen: a single-chamber megalithic tomb with two or more upright stones framing a "portal" at the front and a large capstone. In the Irish classification of megalithic tombs set out by Seán Ó Nualláin and Rúaidhrí de Valera in 1961, portal dolmens are one of four categories, alongside court cairns, wedge-shaped gallery graves and passage tombs.
Most portal tombs date from the Neolithic, between 4000 and 3000 BCE, and some were covered by a mound of earth or smaller stones which has since eroded away, leaving the stone skeleton. Ireland has about 172 dolmens, of which the best known is Poulnabrone in the Burren, with estimates between 3800 and 3200 BCE. Excavation under Poulnabrone found the remains of about 33 people, adults and children, along with stone and bone objects.
In Wales and Cornwall the form is the cromlech or quoit. Pentre Ifan in Pembrokeshire is the largest and best-preserved Neolithic dolmen in Wales. The names of Irish portal tombs often reflect old tradition: Brownshill, near Carlow, has a capstone reputed to be the heaviest in Europe, estimated at 150 tonnes, and Proleek in County Louth is the subject of a legend of a Scottish giant who carried it there.
Dating rests on the few excavated tombs, and most are dated by comparison.
When visiting, look for the capstone and for the portal stones at the front.
