Lambay is the largest island off the east coast of Ireland and is about 2.5 square kilometres in size, and rises to 127 metres.
Still privately owned by the Baring family, Lambay is home to an adapted medieval castle and an Edwin Lutyens-designed estate.
The island is accessible, by prior permission only, from Rogerstown Harbour, 4 km away, 27 km north of Dublin in Rush.
