Nel tempo, e con l’ acqua, tutto muta. (“In time and with water, everything changes” Leonardo da Vinci)

Protecting and conserving coastal and submerged cultural heritage poses particular challenges, firstly in understanding the scope, significance and vulnerability of the site, and then in determining possible solutions. Protection and conservation of a submerging or submerged ruin encompasses a wide range of site-specific measures comprising protection of the coastline, protection and repair of the monument (which could include repointing, reinstatement of rebuilding of sections of collapsed masonry etc), and ongoing monitoring and maintenance requirements.

Harbours of Dalkey Island

Harbours of Dalkey Island

Dalkey Island holds has two harbours – an 1804 boat harbour constructed by the Board of Ordnance to service the Martello Tower and battery, and an undefined medieval harbour associated with the use of Dalkey Sound as one of the entry ports for Dublin. This underwater archaeological survey was carried out with Aisling Collins of ACAS as part of archaeological investigations by ACAS on the island. Surveying submerged and inter-tidal sites require some specialised recording techniques and also draws on a very wide range of historic source material.
