The discovery of one of Roman Londons most significant buildings - its amphitheatre - underneath the medieval Guildhall resulted from major archaeological excavations which took place between 1985 and 1999 as part of the City of London Corporations ambitious programme of redevelopment at the Guildhall. The history of the Guildhall and its precinct from the 12th to the 20th centuries is the subject of a companion volume. This book describes the construction, development and disuse of the amphitheatre, from the 1st to 4th centuries AD. Constructed on relatively low ground in the north-west part of Londinium, the first amphitheatre was built in c AD 74 of timber. Evidence was recovered for the eastern entrance, arena palisade, bank for seating and associated drains. The amphitheatre was rebuilt shortly after AD 120, with masonry foundations and walls, associated with new timber stands. The evidence allows conjectural reconstruction and comparison with other British amphitheatres. Abandoned by the mid 4th century, the amphitheatre was largely demolished and sealed by dark earth. The arena may have survived as an oval depression until the area was reoccupied in the 11th century. Significant finds assemblages include an early 2nd-century dump of glass cullet, lead curses from the arena surface and samian pottery with gladiatorial motifs. The amphitheatres remains are preserved and displayed in the basement of the new Guildhall Art Gallery.

This report presents an overview of Roman urban development in London south of the Thames. The establishment of the Roman bridge and the first approach roads and landing places, made Southwark an ideal location for the development of facilities for the trans-shipment of goods between land and river. The wide range of data from 41 previously unpublished north Southwark sites provides the means for 'mapping' Roman activity in Southwark: the nature of the early settlement, changing patterns of land use and broader processes of social and economic change. Early land reclamation preceded the establishment of a thriving trade centre involved in the redistribution or marketing of locally processed and imported goods, with evidence of a concentration of buildings burnt in Boudican fire of AD 61 along the main road to the bridgehead. Increased land reclamation and construction of more masonry buildings in the 2nd century AD indicate further growth. By the 3rd century large stone buildings at ten of the sites reported suggest an administrative area housing official residences. After the mid 4th century the settlement contracted to the area immediately around the bridgehead with a cemetery on previously occupied land to the south.
