Planned cathedral city laid out on a regular grid of "chequers" (blocks) on the plain below abandoned Old Sarum, with a vast cathedral close and market square
England's great planned medieval new town; shows ecclesiastical city-founding and the deliberate relocation of an entire community to a rational gridded site
Salisbury, or New Sarum, was laid out from 1220 under Bishop Richard Poore, when cathedral and community were moved from the cramped hilltop of Old Sarum to a fresh site on the plain below. The new city was organised on a regular grid of rectangular blocks known as chequers, with water channels along the streets, a spacious market square, and a vast walled cathedral close containing the new cathedral. It was an ecclesiastical foundation planned and developed as a single coherent enterprise.
Salisbury is England's outstanding planned medieval new town and a key example of church-led city-founding, notable for the deliberate relocation of an entire community to a rationally gridded site. It is regularly invoked in accounts of medieval town plantation to show that gridded, regulated urban design was a routine instrument of thirteenth-century lordship and enterprise.
