The Royal Mint says the new visitor centre in Llantrisant, near Cardiff, will allow people to look behind the scenes of the organisation “for the first time in its 1000-year history”.
Visitors will be able to take a tour of the Royal Mint manufacturing and will also be able to visit a range of static and interactive exhibitions, for which designers are currently being sought.
The on-site museum will feature more than 80,000 artefacts.
The new visitor centre is set to open in 2016 and is part-funded by the Welsh Government, which has provided a grant of £2.3 million towards the £7.7 million cost of the project.
Shane Bissett, Director of Commemorative Coin and Bullion at The Royal Mint, says: “The Royal Mint is a highly secure, Ministry of Defence-protected site which is not usually open to the public, with the exception of very special occasions and by invitation only.
“We receive large numbers of requests to visit from members of the public every year and have been exploring the opportunity of a visitor centre for some time.”
The deadline for applications to the exhibition design brief is 22 December. To find out more and apply, visit ted.europa.eu.
