CISMAS was formed in 2004 to promote maritime archaeology in Cornwall and the Scillies and to encourage community archaeology.

Since then, CISMAS has undertaken over twenty projects on sixteen different sites. Comprehensive reports have been produced for all our projects and these can be downloaded from our resource centre.
