Origins and Roman Engineering Marvel

The Roman London Wall was constructed around AD 200 to protect Londinium, the Roman provincial capital. Stretching approximately 2 miles (3.2 km) and enclosing about 330 acres, the wall was a monumental feat of engineering. Built primarily from Kentish ragstone with distinctive horizontal bands of red ceramic tiles, the wall was originally 2 to 3 meters thick and up to 6 meters high. Its purpose was both defensive and symbolic, marking Londinium’s importance within the Roman Empire and safeguarding it against northern tribes such as the Picts.

Medieval Adaptations and St Alphage Church

Following the Roman departure, the wall fell into disrepair but was later restored and heightened during the Anglo-Saxon and medieval periods. The section at St Alphage Garden incorporates medieval stonework and a brick parapet added in 1477 by King Edward IV to strengthen defenses during the Wars of the Roses. Adjacent to the wall stood St Alphage Church, established likely in the 11th century, with the wall forming its northern boundary. The church was closed in the late 16th century and demolished, but its tower remains as a ruin, reflecting the layered history of the site.

Urban Evolution and Preservation

Over centuries, London expanded beyond the wall’s boundaries, and parts of the wall were built over or incorporated into buildings. The area around St Alphage was heavily bombed during World War II, exposing the Roman wall beneath later constructions. The site was transformed into St Alphage Garden, a peaceful public green space that preserves this historic fragment. Nearby, the Salters’ Hall gardens complement the site, managed by one of London’s ancient livery companies, linking the location to the city’s rich commercial and social heritage.

Architectural Features and Archaeological Significance

Visitors can observe the robust Roman masonry with its characteristic tile courses, medieval additions, and remnants of the church tower. This blend of architectural layers illustrates London’s continuous occupation and adaptation from Roman times through the medieval era to the present. The wall’s survival offers a tangible connection to Londinium’s urban fabric and defensive strategies, making it a significant archaeological and historical landmark.
