Geographically, Wicklow Head is the easternmost point on the mainland of the Republic of Ireland. Lambay Island is the easternmost point of the province of Leinster and lies four kilometers offshore from headland located at Portrane. During the Neolithic period, Lambay Island was important as it served as a site for stone quarrying and production. The quarry site was unusual in Ireland as it was the only one with all stages of production ranging from quarrying up to the final polishing.

Lambay Island is home to one of the most vast and significant colonies of seabirds in Ireland. It is home to around five thousand kittiwakes, 2,500 pairs of herring gulls, 50,000 common guillemots, and 3,500 razorbills among others.

1. Lowest Point in Ireland

The lowest point in the Republic of Ireland is the North Slob. This is an area of mudflats situated at the estuary of River Slaney at the Wexford Harbour in Ireland. The area was reclaimed in the 19th century when a sea wall was built and has an area of 1,000 hectares. North Slob is the lowest point both in Ireland and in the British Isles. Of the reclaimed land, 200 hectares have been set aside as a nature reserve known as the Wexford Wildfowl Reserve. The National Parks and Wildlife Service and Bird Watch Ireland manage the reserve. North Slob serves as a winter home to more than 10,000 white-fronted geese. This forms about 1/3 of the world's population of the geese. In summer months, the geese migrate to Greenland. The area earned international recognition in 1984 with the designation of Wexford Wildfowl Reserve as a Ramsar site. The Guinness World records formally known as Guinness Book of Records have its origin in North Slob.
