An Extinction Rebellion logo appeared on the historic Alton Barnes White Horse at the weekend in Wiltshire.
The XR logo, which depicts an hourglass and is synonymous with Extinction Rebellion, was created out of black clothes and material.
Critics have slammed the move, saying it was 'disrespectful' to Wiltshire's famous landmark.
Others were quick to defend the movement, reminding them that the logo was temporary, and only made from T-shirts.
Members of the climate activist group, Extinction Rebellion Vale of Pewsey have called it a piece of 'flash art'.
The leader of Wiltshire Council, Philip Whitehead has criticised the 'protest'.
The logo has now been removed, with protesters saying there was no trace of it ever being there.
