Jacobs Island is a picturesque site nestled in Lough Mahon, Cork.

Development Commenced 2003

Jacobs Island is a picturesque site nestled in Lough Mahon, Cork. A stunning waterfront development on the Douglas Estuary accessed off the South Ring Road at the Mahon Interchange, immediately south of the Jack Lynch Tunnel.

Lying within the city boundary with an extensive shoreline, these impressive 41-acre site views are second to none, just 30 minutes bus ride and a 25-minute cycle to Cork City Centre.

The development commenced in 2003 and includes approximately 600 residential units, comprising 184 apartments and 160 houses, including detached and semidetached houses. The site boasts an impressive 41 acres with extensive shorelines that offer unparalleled views of the area.

The history of the Jacobs Island site in Mahon dates back to the early 1970s when it was owned by Irish Steel. The site was used for the manufacture of steel and other industrial purposes. However, the Irish Steel plant closed down in the early 1980s, and the site remained unused for several years.

Jacobs Island – Over the years

The first residents arrived in the Bronze Age. In the seventeenth century the Crawford family, who were well known local brewers and merchants, set up a home here at Lakelands House in Mahon. The Crawfords were responsible for many improvements in Cork during the nineteenth century and were great benefactors to the City. They were responsible for the construction of the Crawford Art Gallery which was gifted to the City. The Crawford family lived in Lakelands from 1792 until the 1920s. The house has since been demolished all that remains is the wine cellar. The cellar has been preserved for future generations.

The family was also very successful when it came to horticulture where they excelled in growing tender shrubs and trees in greenhouses and around the property. The rare trees and shrubs which family members would collect through extensive travel would be imported to be planted at Lakelands. As described by William Horatio Crawford, Lakelands was a perfect arboretum…richly planted…with rare shrubs and trees. Crawford’s plantings are included Himalayan and Andean specimens, such as magnolias, rhododendrons, and cordylines. 

On the property, a group of gigantic Chilean monkey puzzle trees marks the site of the house itself. To this day Jacobs Island has a unique nature aspect and has a wide array of wildlife growing all around it with accompanying views looking out onto Lough Mahon.

Jacob’s Island – a well-connected urban lifestyle in an exclusive location

In the early 2000s, McCarthy Developments planned to redevelop the site into a modern waterfront development. Construction work commenced in 2003, and the development was completed over several phases. The first phase of the development included the construction of residential units, including apartments and houses.

Today, the Jacobs Island development is a thriving community with a range of amenities and attractions, including parks, shops, restaurants, and cultural attractions. It is a popular location for residents and visitors alike who enjoy the natural beauty of Cork Harbour and the convenience of its location.


Overall Jacobs Island offers the perfect balance between urban convenience and exclusive waterfront living, making it an ideal location for those seeking a highquality lifestyle in a stunning location
