No trace remains of the cemetery as it was cleared in 1962 and the news reports below say some remaining headstones were removed in 1978 (although locals say they were still there well into the 1980s)
The site is vast and over 11,000 people are buried under the park including Sir Hugh Gilzean Reid (founder of the Evening Gazette), ironmaster John Gjiers and the children of ironmasters Bolckow and Vaughan.
A great deal of research has been done into the site by Steve Waller which you can read about on the Northern Echo and Evening Gazette websites.
Amazing theres currently absolutely nothing in the way of signs or memorials, so its unfortunately another example of Middlesbrough forgetting its past.
Thanks to Peter Edwards for pointing this one out, there may still be a display in the entrance of the Teesside Archives, but I don’t know if its still there.
