Calliagh:
Wedge-tomb
H 634 277
Sheet 28
About 8 km SSW of Monaghan
town, on top of a drumlin (hillock) about 250 metres NE of a
transmitter, beside an old laneway leading N from a by-road
from which the tomb is visible, this tomb is ruined but interesting.
It is built of large stones, and has a gallery 7.5 metres long,
with remains of double walling on the S side. Roofstones have
been displaced. To the S of the entrance, and within the area
of the cairn (some of which survives), is a large and tall stone
of unexplained significance.
~ 2.5 km WSW is a court-tomb
in Carn (see under Garran, below).
~ 4 km WSW is Garran
portal-tomb.

Edergole:
Court-tomb
H 615 196
Sheet 28
Just over 3 km NNE
of Rockcorry, 400 metres W of Edergole school, by the N side
of a by-road which has cut through the tomb, part of it is incorporated
in the road-fence. Part of the gallery, however, composed of
very large boulders, survives - plus one roofstone 2.1 metres
square, raised on jambs to a height of 1.5 metres. The SW end
of the gallery, and the court, have been swallowed up by the
road. It is very surprising that anything of the tomb at all
remains, because many such tombs (perhaps dozens or scores)
were demolished to provide road material and stones for other
edifices.
Garran: Portal-tomb
H 597 257
Sheet
27
About 50 metres W of
the Monaghan-Newbliss road, incorporated into a field-wall behind
a two-storey house some 8 km NE of Newbliss, this is one of
the best monuments in Monaghan. Steps lead up the wall and then
down between the portal stones to the chamber of this tomb (1.8
metres by 90 cms) which remains intact despite the slipping
of the large capstone, 2.4 metres long and one metre thick.
It is composed of eight stones, including two portal-stones
1.5 metres high (the right-hand one split in two) and a low
back-stone - but no door-stone.
~ 1.5 km E by N and
about 50 metres N of a lane in Carn (H 610 260) is a
court-tomb with a wedge-shaped cairn 35 metres long. The façade
of the U-shaped court is well-preserved, with large orthostats
flanking the portal-stones. The lintel over the entrance lies
in the first chamber of the three-chamber gallery.
~ About 3.2 km N by
E of Garran portal-tomb, in a field at the end of a farm lane
running W from the main road in Tiredegan (H 602 286)
is a double-court tomb, much of whose cairn survives to a height
of over one metre. Some of the stones of the E court still stand,
and a large lintel still rests on the portal-stones. Only one
large chamber (1.8 metres wide and 5 metres long) is traceable:
details of the W end of the tomb are obscured by cairn material.
Some of the kerb on the S side projects above cairn-spill.
~ 6.5 km NNW of Garran
portal-tomb in Clogherna (pronounced 'Clarna', H 580
287) is another double-court tomb, rather ruined, but retaining
one of its galleries, over 5 metres long and composed of large
orthostats including a backstone 1.2 metres high.
Lennan:
Portal-tomb
H 746 235
Sheets 28 and 28B
Picturesquely visible
up a slope from a by-road, the fine, pitted capstone of this
tomb has slid back, taking the portals with it, so that it is
now just a little cave acting as a field-dump. The portals have
very beautiful quartzite banding in their stone.
~ 2.2 kms SSW in Dunmaurice,
just behind a house (H 741 214) and surrounded by the usual
plastic sacks, rusting metal, old drums, wire, tractors etc.,
are the sad remains of a court-tomb: just a pair of jambs and
a fine lintel in a rural slum.
~ 5.5
km NE in a tiny copse in Croaghan (H
797 256) are the interesting remains of a complex structure
containing seven separate two-chambered galleries which are
only roughly parallel, through which a short track has at
some (possibly prehistoric) time been driven, because it is
lined with fine megalithic orthostats or roof-stones. Only
excavation could determine the chronology of these tombs,
but it seems like one court-tomb became, possibly over a period
of hundreds of years, a complex monument. Stone for at least
some of the galleries came from an outcrop nearby which the
visitor will pass. The name of the townland in Irish must
refer to this interesting and anomalous monument.
~ 5 kms N of
Croaghan is the fine standing-stone at Mullyard in
county Armagh.
Lisnadarragh:
Wedge-tomb
H 734 077
Sheet 35
Close
to a minor road, 2 km N of Shercock, this roofless but impressive
ruin looks like giant false teeth. There is a marked decrease
in the size of the orthostats from front to back (SW to NE),
and a single roofstone lies to the SE of the relatively narrow
gallery.

~ 2.5
km WNW in Corcreagh, also near the road (H 699 082),
is Labbyfirmore or 'The Big Man's Bed', a ruined and
overgrown court-tomb. All that can be seen are the N (front)
end of the gallery: a large displaced roofstone resting on a
sidestone, and three stones at right angles nearby which are
the remains of a subsidiary chamber opening to the W.
~ 7.5
km SW (6.5 kms WSW of Shercock and 6 kms NNW of Bailieborough,
in county Cavan) is another, larger wedge-tomb at Drumeague
(H 667 028), also roofless, but with a fine door-slab still
in situ, the buttress-stones, and most of its double-walling.

Mullyash:
Passage-tomb
H 869 259
Sheet 28
Easily accessible by
a forest track, but regrettably surrounded by dreary exotic
conifers, this tomb commanded magnificent vistas before forestation:
to Slieve Gullion, Loughcrew, the Mourne and Carlingford
Mountains. The site was until circa 1950 a site for Lughnasa
celebrations. A standing-stone, probably once connected with
the celebrations lies broken (by Christians in a long, but erratic,
tradition of smashing 'idols'?) some 200 metres W. A stepped,
two-tiered cairn with some of its original facing intact, and
closely resembling that of Newgrange before it was tarted up,
almost certainly contains a passage-tomb.
