Fencing and graffiti-covered shipping containers have appeared next to Redcliffe Caves in Bristol.
The car park at Redcliffe Wharf, next to Redcliffe Bridge, has been partially closed for the past few days and is likely to remain so for at least another week.
Bristol Live has been advised that the new additions are at least in part linked to filming of a television series.

Pedestrians and cyclists are still able to get past to The Ostrich and beyond.
Many of the containers have been decorated with bright graffiti art, which are visible from the bridge below the brightly-coloured row of houses along Redcliffe Parade West.
The landowner, Bristol City Council, said the site is temporarily being used for storage for various work projects ongoing in the area.
It said this is likely to be ongoing until June 25, and clarified that it is not linked to the redevelopment of the site.
Complex Development Projects Ltd (CDP) is set to build a mixed-use development on the land, which is currently home to three derelict buildings including one damaged by fire in 2018.
The waterside site is widely considered to have untapped potential, particularly compared to other thriving areas along the Floating Harbour.
Planning permission for the regeneration was granted in 2017, and updated permission was refreshed in April of this year, but construction work has not yet started.
'Television filming'
A spokesperson for the developer added: "The current activity on the site is relating to the filming of a TV series .
"The works are nothing associated with the development proposals."
It is not yet clear which television series it relates to, but there are several major productions currently being filmed around the city.
According to council planning documents, the land has been vacant since the boat building company there moved out in July 2013, to relocate to the Albion Dockyards.
It has since been used informally for parking and storage related to public events and filming in Bristol.
In September the same site was used for the filming of Netflix science fiction series The Last Bus.
