Along the route we visit Calleva Atrebatum, originally an Iron Age settlement, capital of the Atrebates tribe, and later, a town in the Roman province of Britannia. Its ruins lie to the west of, and partly beneath, the Church of St.Mary the Virgin, just within the ancient walls, and about a mile east of Silchester village.  The Iron Age town was on the same site. We pause at the amphitheatre (A.D.70-80) just outside the city walls.  The afternoon takes us around, and into Pamber Forest, a 478 acre Ancient Woodland, owned by the Benyon family's Englefield Estate since 1745.  The Forest is a remnant of The Royal Forest of Windsor, dating back to, at least, Norman times, when it was a Royal Hunting Ground.
