Built in the C13th century to protect the expanding town from Scottish raiders, Newcastle’s Town Wall was an impressive structure. It was approximately 3km / 2 miles long, up to 2m / 7ft thick and approximately 7.6m / 25ft high. It enclosed the Castle and its Black Gate as well as the main medieval commercial district along the quayside and all the ground northwards to St. Andrews Church. The wall had seven main gateways, 17 towers and 30 turrets. A section of the Wall was extended along the quayside to protect the properties of wealthy merchants from water-borne attack.
Only short sections of the curtain wall now survive as much was demolished in the C19th to aid redevelopment and access. Only five of the original towers have survived.
