Out here on the remote eastern edge of England, two thousand years ago the Romans built a fort to defend the entrance to the river Blackwater. When they left, the fort fell into ruins. In 654 St Cedd built a church on the ruined walls of the Roman fort, St Peter-on-the Wall. This is the last part of that Saxon Church still standing and it is still in use, the door is never locked and people still come. Meanwhile, the setting sun pours out its nuclear fusion energy towards the decommissioned Bradwell nuclear power station behind me. Windmills spin out energy torn from the wind and the turbulent North Sea pounds against the sea wall. This is a powerful place in many ways, a fusion of power, spirits and all that has gone before.
