Overview

History & context

Portus Dubris (Dover) was the principal cross-Channel harbour of Roman Britain and the headquarters of the Classis Britannica, the British provincial fleet. A succession of forts occupied the site: an early timber-phase fort begun c. AD 117 but apparently never completed, followed by the main stone-built Classis Britannica fort (c. AD 130–210, occupying roughly 1 hectare), and later a substantial Saxon Shore fort of the late 3rd century built partly over the earlier installations.

Significance

Historical significance

As the shortest crossing to Gaul (to Gesoriacum/Boulogne), Dubris was the strategic and logistical hinge of Britain's connection with the Continent, serving both as a naval base and as the British terminus of Watling Street. Its twin Roman lighthouses (pharoi) flanking the harbour — one of which survives within Dover Castle — are unique upstanding monuments in Britain.

Archaeology

Archaeological record

Extensive rescue excavations in the 1970s by Brian Philp revealed the Classis Britannica fort with its tile-stamped CL BR roof tiles, granaries, principia, and adjacent extramural buildings including the famous "Painted House" — a 2nd-century mansio with the most extensive in-situ Roman wall paintings north of the Alps. Subsequent work has clarified the Saxon Shore fort's plan and traced the silted Roman harbour beneath the modern town
