SEGONTIUM (SIRGONTIUM) - Northumberland & Northeast
Segontium, often referred to as Sirgontium by the locals, is one of those wrecks we’ve returned to time and again. It’s a fishing vessel, 30.5 metres long, sitting upright at 29 metres. She went down in 1984, so she’s had plenty of time for the ocean to reclaim her. We love how intact the structure remains, considering the often-turbulent Northumberland waters. You can still make out the wheelhouse, the hold, and even parts of the deck machinery, all encrusted with dense plumose anemones, their white tentacles swaying gently in the subtle current. Dropping down, the visibility can be a bit hit or miss, but when it’s good, the sheer density of life here is impressive. Ling often lurk in the shadowed corners of the hold, and conger eels peer out from beneath collapsed sections of plating. Our favourite spot is exploring the stern, where you’ll find huge clusters of dead man's fingers coral and, if you’re lucky, a curious grey seal might make a fleeting appearance. It’s a fantastic dive for experienced wreck enthusiasts who appreciate a historical vessel colonised by thriving marine life. The Segontium might not have the dramatic history of a battleship, but its character and the life it now supports make it a truly rewarding dive.
