Grosmont Tunnel was built as part of George Stephenson's horse-drawn railway that ran between Whitby and Pickering, which was completed in 1836. The tunnel is still in use today, with a footpath replacing the rail track.
The horse-drawn railway naturally operated at fairly low speeds, so the earthworks or structures needed were minimal. There were some timber bridges but these have now been replaced.
The 119m long tunnel is 3m wide by 4.3m high, with turrets and castellations on the portals. It was completed around 1834, and trains ran twice daily between Grosmont and Whitby from June 1835. A return journey took six hours.
When steam traction came to the railway in 1847, a larger running tunnel was constructed alongside the original.
Grosmont Horse Tunnel is probably the oldest railway tunnel in Britain.
