The Dents Holt pit was a mid 18th century working potentially owned by the Ridley family, as were many in the area at that time. The only reason we know of its existence is became it's known to have featured two 42" cylinder Newcomen pumping engines in 1745 as per the Early Engine database. Byker is known to have featured the first of these engines on the whole of Tyneside, with the Engine Pit (around the site of Byker Metro Station) having the first in 1718.

The exact site of the Dents Hole pit is not known, but we can take a good punt given the tiny area it could be located at. Dents Hole was a small salmon fishery near St Peters which is now extinct. We can cross reference with the Coal Authority map, which shows a mine entry located at The Oval just off Bakewell Terrace. This is the most likely site of the working.

It had totally vanished by the mid 19th century.
