The lost city of Old Sarum, is a rewarding site for groups to explore. Iron Age people first raised the great encircling ramparts. Anglo-Saxons and Normans later settled within them, while the Romans built a substantial settlement adjacent to it. Creating a castle at the core of the vast hilltop fortress. William the Conqueror summoned the richest landowners of England here to pay him homage in 1086. A Norman cathedral was also raised here, before the city was abandoned in favour of Salisbury. Today Old Sarum is a magical place, with seasonal wild flowers and striking vistas over Salisbury Plain.
