The Scottish Crannog Centre roundhouse near Kenmore appears to have been all but destroyed in a devastating fire.
Images from the scene show the wooden building – created as a replica of an Iron Age water dwelling – consumed by flames late on Friday evening.
John Ward, posting to the Aberfeldy Community Notice Board on Facebook, shared video showing flames erupting from the fragile structure.
The Aberfeldy businessman spotted the flames shortly after 11pm when he was driving to collect his son.
Speaking to us in the early hours of Saturday, Mr Ward said: “The structure was still glowing red when we left. But … it’s totally gone. There’s nothing left other than a few sticks in the water.”
The 57-year-old added: “Everyone was just in shock looking at it. It’s going to be devastating for the community.
“It’s just a shock to everybody.”
A spokeswoman for the Scottish Fire and Rescue Service confirmed crews had been called to a blaze in a building north of Kenmore but was unable to provide any more information at this stage.
