A World War One cruiser sunk off Rathlin Island has been made a listed monument.
HMS Drake was torpedoed by a German U boat off the island in 1917 with the loss of 19 lives and went down a short time later in Church Bay.
It has been a popular dive site for many years.
The listing will mean that divers can still access the wreck but will not be able to remove anything from it.
The remains of the ship are considerable with anchors, guns and steering gear still intact and clearly visible.
Senior archaeologist with the Department for Communities Liam McQuillan said the designation gave the wreck its proper recognition “as a site of national importance”.
There will be no exclusion zone and the listing will not mean a licensing system for dives.
Marine Archaeologist Rory McNeary from the Department of Agriculture Environment and Rural Affairs said he would “actively encourage divers to visit the site but to take photos rather than souvenirs”.
Three lighthouses on Rathlin are also being protected, including the oldest one on the island, the East Lighthouse.
It has stood on Rathlin for the last 150 years.
The West Lighthouse at the RSPB sea bird centre has been given a Grade A listing.
