Historians fear one of Britain's most famous landmarks, Stonehenge, could see it's World Heritage status revoked if the government builds a tunnel under it.
People living near the site have been fighting for years to ease the traffic congestion that brings the roads around Stonehenge to a standstill.
Campaign groups say the move would be disastrous for tourism, possibly damaging Stonehenge irrevocably.
A decision will be made about the tunnel in the next few days.
"Maybe this has galvanised them, hearing each other's stories and knowing they are not alone," say the nurses behind the Facebook group, New Zealand, please hear our voice.
