Arbeia Roman Fort in South Shields is celebrating its 30th anniversary.
The unique Roman reconstructed West Gate at Arbeia turns 30 this month.
It was officially opened by the Duke of Gloucester on 6 April 1988 and is the only reconstructed Roman gateway in the UK erected on its Roman predecessor's actual remains.
Inspired by Roman reconstructions like the famous 19C Roman fort at Saalburg in Germany, the ambitious reconstruction was the result of years of extensive research and planning.
The stone masons that were employed in 1988 had to be retrained by the team at Arbeia to create the West Gate using Roman techniques.
Arbeia's other Roman reconstructed buildings were created at a later date.
They include the Commanding Officer's House and soldier's barrack block, all also created on their original foundations.
Last year £280,000 worth of improvements were made to the visitor attraction, which so far has seen new visitor information, navigational paths and platforms put up around the fort remains.
