The Carrowmore Circles.
County Sligo is home to the largest and oldest collection of stone circles and dolmens known from neolithic Ireland. These are found at Carrowmore, a collection of burial monuments at the centre of the Cuil Iorra peninsula three kilometers west of Sligo town.
Carrowmore is currently closed. Entry to the Carrowmore complex was free for the 2020 season, due to Covid 19 restrictions. Please note, there is no access to toilets or the visitor centre, and dogs are not allowed on site.
The Carrowmore complex is located at the heart of the Cuil Iorra peninsula, a parcel of land bounded by water
on three sides. Ballisodare Bay lies to the south, the Atlantic ocean to the
west and Sligo Bay to the north. Lough Gill is to the east beyond Carns Hill, connected to the sea by the short shelly Sligo river, the Garavogue.
The stunning cairn topped mountain of Knocknarea is four kilometers to the west of Carrowmore, while the smaller, but equally important Carns
Hill is four kilometers to the east. There are more neolithic monuments on the summits
of the Ox Mountains to the south.

Thirty monuments remain at Carrowmore today, in varying states of preservation and completion, the most perfect being the Kissing Stone. The antiquarian George Petrie
noted 65 monuments during his visit for the Ordinance Survey in 1837, but today the number is thought to be considerably lower at a probable maximum of forty circles. The sites
were badly damaged in the early years of the nineteenth century
by land clearance and gravel quarrying.
This website provides a virtual tour of the monuments at Carrowmore, with a page
for each monument and its history of research. New information from ancient DNA suggests that the monuments were built and used by people who came by sea from Brittany in north-western France slightly over 6,000 years ago.

These voyagers brought the first cattle and sheep to Ireland, and existed by herding their flocks through the forested landscape. They also re-introduced the red deer to Ireland, the native species of Irish elk having become extinct after the last ice age. The oldest remains of red deer currently known on this island are the carved antler pins, one of the most common items found within the Carrowmore chambers.
Because so many of the monuments have been destroyed and disturned, the remaining records of some
circles are the comments by George Petrie from 1837, the excavations by Wood-Martin and the illustrations
of William Wakeman from the 1880's are extremely valuable. A series of amazing photographs of the Carrowmore monuments were taken by Robert Welch in 1896 and W. A. Green in 1910.

Carrowmore is managed by the Office of Public Works, and there is a small visitor
centre which is currently closed; however, the grounds are open, with
no entry fee.

The Monuments
The type of monuments found at Carrowmore are boulder circles with central dolmens and sometimes rudimentary passages. They are among the earliest megalithic of chambers built in Ireland; information from carbon dated red deer antlers show that the chambers were used between 5,800 and 5,000 years ago. Originally each of the sites had a raised platform or tertre, which was up to
a meter above the surrounding ground level, sometimes with one or more inner circles of smaller stones.

The
stones used to construct the monuments are a very hard form of glacial rock
called gneiss, which comes from the nearby Ox Mountains. There are an
average of 30 to 35 stones in each circle, set side by side and placed standing upright like teeth.
The Carrowmore circles are 10 to 12 meters in diameter on average, though a few monuments such as 19,
22, 27 and 51 are much larger.
The Kissing Stone, or Leaba na Fian is the most intact example remaining today. It consists of a circle
of boulders about eleven meters in diameter, and has a beautifully graceful dolmen, or stone table at the centre. The Kissing Stone is built on a slope and has an amazing view west to Knocknarea Mountain.
The sockets of missing stones were
found during the excavations, which show that there was once a short passage
leading into the chamber. About 14 of the monuments have remains of passages at Carrowmore.
It seems that in some cases
the larger boulders were split in half, a feature that can be seen
in the chamber of Site 27. The rock is rich with
veins of quartz, and was carried to the site by retreating
glaciers during the ice age.
Several fields of gneiss boulders lying as
they were dropped by the galciers can be seen to the south of Carrowmore and on the south slopes of Knocknarea, which give an impression of what Carrowmore could have looked
like before the circles were built.
The Coolrea peninsula is limestone covered with a mantle of glacial
gravel. The complex is located on a plateau at the centre of the peninsula,
with the circles built around the edge. Some limestone slabs were used
in the monuments, but few compared to the more plentiful gneiss boulders.

A good
example is the massive capstone on the chamber at Site
51, which may have been quarried at the
Glen in the south slope of Knocknarea.
Fragments of quartz
were found in some of the circles, and these would have come from the
Ox Mountains to the south, specifically from the area around Croghan.
One small piece of rock crystal, discovered in Monument Number 3, has a hole drilled through the end and was probably used as a pendant or pendulum.
There is no evidence that stone cairns ever covered the dolmens at Carrowmore; instead they appear to have been an early free-standing form of passage-grave, with the chamber supported by a platform or tertre. The exception is the central focal monument, Listoghil, which was free-standing when built, than buried in a great cairn of stones, possibly around 3,400 BC.
