THE opening of Sir Richard Branson’s first Virgin Hotel in Britain has been delayed by a year – after archae-ologists at the site in Edinburgh unearthed artefacts dating back 1000 years.

The excavation, at a site in the Cowgate, has lasted more than a year, three times longer than expected, due to the range of objects and material discovered from the 10th century.

Experts say the remains of buildings found predate Edinburgh Castle and the creation of the town burgh by David I by around 200 years.

The work has also unearthed ditches and walls marking the original boundary of the city and some of the discoveries could date as far back as the Bronze Age.

The findings are expected to become a major selling point of a stay at Branson’s first hotel in the UK, which will boast 225 rooms and create more than 300 jobs.

During a 60-week excavation, a human skull, a drinking vessel, shoes, jewellery, and knives, along with a ball used in a giant catapult and an early cannonball were discovered.

Hearths, wall panel, structural timbers, rubbish pits and wells have also been unearthed during the dig by the Virgin team working on it.

The plans for the hotel at the India Buildings on Victoria Street and an adjacent gap site were announced in February of last year, with a 2020 opening date.

But Virgin Hotels said work would finally begin at the site “within weeks,” with the aim of the hotel now opening in 2021.

Edinburgh City Council archaeologist John Lawson said: “This has been one of the most significant urban excavations ever undertaken in Scotland. We have found everything we could have probably hoped to

find on an excavation like this – there was basically 1000 years of archaeology on the site. The full analysis and research has still to be done, but the results of the work have been tremendous, in terms of scale and quality, and the preservation is outstanding.

“For the first time ever, we have found a series of buildings which pre-date the formation of the medieval town in the 12th century.

“There are a great sequence of layers on the site which almost tell the story of Edinburgh in microcosm.”
