Old Sarum Cathedral
Salisbury, United Kingdom · built 1066
Old Sarum Cathedral was a Catholic cathedral at old Salisbury, England, now known as Old Sarum, between 1092 and 1220. Only its foundations remain, in the north-west quadrant of the circular outer bailey of the site, about 2 miles (3.2 km) north of its 13th-century replacement, Salisbury Cathedral. The cathedral was the seat of the bishops of Salisbury during the early Norman period and the original source of the Sarum Rite.
