The Roman Baths in Bath have been given a deep clean ahead of the attraction reopening.
All 250,000 litres of hot water from the Great Bath were drained before it reopens on 6 July.
Staff then scrubbed the entire bath as part of regular maintenance to prevent it from becoming murky and to stop algae growing.
Social distancing measures have also been implemented ahead of next week's opening.
A one-way system has been installed throughout the site, as well as clear screens in reception areas, hand sanitation stations and staff marshalling at key points to ensure visitors keep two metres apart.
The attraction will also run at a maximum of 30% of normal capacity in terms of visitors, who must pre-book before attending.
Councillor Paul Crossley, cabinet member for community services at Bath & North East Somerset Council, said group visits would not be allowed "for the time being".
Mr Crossley said: "We've been working hard to ensure visitors have a safe and enjoyable experience and people can still expect a visit steeped in history and a smiling front of house team to greet them.
"People can enjoy the space and make the most of discovering the remarkably preserved remains of the ancient spa and the museum collections."
The Roman Baths is visited by more than a million people every year.
The site, which is run by Bath & North East Somerset Council, consists of the preserved remains of one of the greatest religious spas of the ancient world.
The city's unique thermal springs rise in the site and the baths flow with natural hot water.
