Dún Laoghaire Harbour and Carlisle Pier were constructed in the nineteenth century for the purposes of sheltering ships and accommodating the mailboat which sailed between Dún Laoghaire and Holyhead. The nearby settlement of Dún Laoghaire has also previously been known as Kingstown and also as Dun Leary. Carlisle Pier has been known previously as Kingston Pier and the Mailboat Pier.
