The publication of the Dalkey Islands Conservation Plan 2014-2024 was launched in Dalkey Castle by the Cathaoirleach Cllr Carrie Smyth on Tuesday 3rd June 2014 in Dalkey Castle.  The conservation plan is used to guide the management of the Dalkey Islands and its significant ecological, archaeological, architectural and cultural heritage. The islands contain evidence of human settlement going back to the mesolithic period (7500-4000 BC) a promontory fort, the early medieval St. Begnet’s church, ancient crosses carved into the granite, and a Martello tower and Battery. The islands support a nationally important tern colony and other protected bird species, and a range of terrestrial and marine habitats.Dalkey Island heritage
