A MAJOR royal residence has been encircled by a ring of steel over a plot to storm the grounds in three days of chaos.
Pictures revealed preparations on The Long Walk just outside Windsor Castle ahead of a planned Extinction Rebellion protest.
Extra security barriers have been put in place to stop the eco idiots getting close to the gates of the castle.
Residents, dog walkers and tourists have all been advised to avoid the area from August 30 to September 1.
It was previously revealed XR activists plan to create a diversion on The Long Walk which would allow members of the group to break into the castle grounds.
A leading security and risk assessment organisation infiltrated XR group chats where the mass demonstration was discussed.
The non-violent action was also planned during a zoom meeting.
An investigator, who posed as an activist, listened as environmental zealots talked about the demo.
A risk assessment by a local business also revealed XR organisers are encouraging elderly and disabled activists to attend.
The eco rabble previously announced they would stage a mass occupation outside Windsor Castle to protest against the King — even though he is a green campaigner.
Climate activists claimed it is the "embodiment of a broken and unjust system".
Extinction Rebellion says its occupation of Windsor Great Park is to urge the King to do yet more on green issues.
The protest, called Upgrade Democracy, will not specifically target the King or any individual, it claims.
Catherine Bartlett, of Extinction Rebellion UK, said: "Windsor Castle has been chosen as an embodiment of a broken and unjust system where our message will resonate powerfully.
"We demand better at all levels; from the head of state to local councils but our central demand is for a Citizens' Assembly on Climate and Ecological Justice, which is needed more urgently now than ever before."
