There’s not a huge amount to see now, but Old Sarum has been an Iron Age hillfort, a Roman settlement and a Saxon residence. That’s all before the Norman Conquest of 1066, which really put the hill on the map. At its height, it boasted a Norman castle, cathedral and town, and served as a religious and administrative hub. As time wore on Old Sarum fell out of favour thanks to tensions between the church and the garrison, and the difficulties of the exposed hilltop terrain. In the 13th century, the cathedral was moved to the nearby town of Salisbury.
