 It is approximately 4.5 mi long by 2 mi wide, with an area of about 3540 acre .
 It has a huge area of shallow water with nearly two-thirds of its area being less than 25 feet (8 m) and almost half of it being under 10 ft deep.
 Lough Ennell produced Ireland's largest ever lake brown trout at 26 lbs (11.8 kg).
 Lough Ennell is dotted with islands, many of which have now become attached to the shoreline as the levels of the lake have changed.
 The main river flowing into Lough Ennell is the River Brosna, which enters on the Mullingar side of the lake and exits on the opposite side at Lilliput.
 Lilliput and Lilliput House were frequently used by Jonathan Swift as a holiday home and place to write, local tradition states that Jonathan Swift was in a boat on the lake when he looked back at Lilliput and noticed how small the people looked at that distance, hence the inspiration for his most famous book "Gulliver's Travels".
 Lilliput at the time was called "Nure" however after the publication of Gulliver's Travels locals began to refer to the lakeshore as Lilliput, the name stuck and today the area is known as Lilliput.
Ballylumford Dolmen is situated on Islandmagee, County Antrim, Northern Ireland, near the north-west tip of the Islandmagee peninsula and near Ballylumford power station.
 It is known locally as the "Druid's Altar", and could be 4000 years old, or the remains of an even earlier passage grave.
 The dolmen consists of four upright stones, with a heavy capstone and a fallenstone within the structure.
 This may have been put there to block the entrance to the tomb.
 The dolmen is in the front garden of a house.
 Historical artifacts have been recovered from under the dolmen by archaeologists and it would appear to have stood over a burial chamber from ancient times.

 A wall plaque at the site describes the dolmen as a single chambered grave erected about 2000-1600 BC.
 Local finds indicate occupation of the neighbourhood during the Bronze Age.

Maigh Seóla (] ) was the territory that included land along the east shore of Lough Corrib in County Galway, Ireland.
 It was bounded by the Uí Maine vassal kingdom of Soghain.
 Its rulers up to the 1220s were the Muintir Murchada, who took the surname O'Flaherty.
 They were based at Loch Cime (later called Lough Hackett) until forced west of Lough Corrib during the de Burgo led English invasion of Connacht in the 13th century.
 According to the 17th century historian Ruaidhrí Ó Flaithbheartaigh Maigh Seóla was considered part of Iar Connacht prior to the 13th century Anglo-Norman invasion of Connacht.
 After the de Burgo / Burke family became established in Maigh Seola the territorial term Iar Connacht was only used to denote the territory of the O'Flahertys west of Lough Corrib and Lough Mask.
The River Erne ( , Irish: "Abhainn na hÉirne" or "An Éirne") in the northwest of Ireland, is the second-longest river in Ulster.

 For 30 miles from Crossdoney in County Cavan to Enniskillen in County Fermanagh, it is difficult to distinguish the river as it winds its way through interconnected loughs or parts of loughs nestling among the drumlin hills of Cavan and south Fermanagh.
 The river is 120 kilometres long and is used for fly fishing for trout and salmon, with a number of fisheries along both the river itself and its tributaries.
 The town of Enniskillen is mostly situated on an island in the river, between Upper and Lower Lough Erne.
 It is linked to the River Shannon by the Shannon–Erne Waterway.
