Flat Earth believers have rented a shop in Inverness in a bid to promote their theory.
The campaign group, called The Flat Earth, posted a list of 50 questions on the window which attempt to debunk the widely accepted fact that the earth is round.
Among the list, it calls into question are the earth’s curvature, orbital movement and the evidence of gravity.
At the top of the message it states: “You have been lied to.
“We do not live on a spherical rock hurtling through a vacuum.”
The door shutters are down but inside the premises are sofas, a television, a bookcase and a chessboard, as well as a kitchen.
Inverness West councillor Alex Graham said that anything to boost occupancy of the several empty shops on Greig Street in Inverness should be welcomed.
He said: “I am not aware of this development myself.
“Personally, I do believe the Earth is round, but people are very much entitled to have a different view on that as long as debate is peaceful.
“Unfortunately, Greig Street has had several empty shops recently and anything that helps boost the occupancy is to be welcomed.”
Graffiti claiming the earth is flat has appeared on road signs in Inverness and on the A9 Thurso-Perth road last year.
In September, police confirmed that they were investigating a positive line of inquiry as they attempted to track down those responsible for the vandalism.
The slogan was spray-painted on the side of buildings and signposts across Inverness, appearing in areas such as South Kessock, Howdens Garden Centre and Daviot Wood picnic site.
The same graffiti also appeared at Inverness Caledonian Thistle’s stadium and off the Aviemore ski road, and spread as far south as Livingston.
