A Devon tourist attraction has applied for a marriage licence to hold weddings in its caves, which date back more than 500,000 years.
Some of the chambers can hold up to 80 people
Kents Cavern in Torquay has applied to Torbay Council for the licence.
If successful, the show caves could be able to host weddings and civil partnerships as soon as April.
The caves are Britain's oldest scheduled Ancient Monument, with English Heritage designation dating back to 1957.
James Hull, general operations manager at the cavern, said: "Show caves throughout Europe have wedding licences and it seems to be quite popular, especially for people looking for something a bit different or second marriages.
"Our chambers vary in size and we have pretty much applied for a licence for most of the caves.
"People would be able to have quiet, intimate ceremonies for 15 to 20 people in one of the smaller chambers, or some of the chambers can hold up to 80 people watching the wedding."
Christine Howle, Torbay's deputy superintendent registrar, said: "It is fantastic news that Kents Cavern has applied for a licence to become an approved venue to hold civil marriages and partnerships.
"If Kents Cavern's licence is granted I'm positive that this unique venue will prove very popular."
Kents Cavern became a Scheduled Ancient Monument giving the site a statutory scheduling by English Heritage in 1957.
The hillside, woodlands and the internal landscape of the caves are designated a Site of Special Scientific Interest under the statutory regulations of English Nature.
