Site Overview

History & Significance

Fishbourne Roman Palace is the largest known Roman building in Britain and one of the most impressive Roman residences north of the Alps. Discovered accidentally in 1960 during water-main laying, the site preserves the remains of a palace of astonishing scale: four wings surrounding a formal garden courtyard some 100 metres square, its north wing alone containing over 50 rooms. The palace was constructed around AD 75, replacing an earlier military and administrative complex at the head of Chichester Harbour.

Fishbourne preserves the finest collection of in situ Roman mosaic floors in Britain, including the celebrated Cupid on a Dolphin mosaic in a room attributed to a young occupant of the palace. The formal garden has been partially replanted using evidence from soil marks and pollen analysis to recreate the bedding trenches of Roman box hedging. The identity of the palace's original occupant has long been debated: the British client king Tiberius Claudius Cogidubnus (also known as Togidubnus), who was granted Roman citizenship and remained a loyal ally of Rome, is the most compelling candidate. The palace was damaged by fire around AD 270 and never rebuilt, its ruins later quarried for building materials.

Why it matters

The largest and most complete Roman palace in Britain, Fishbourne provides unparalleled evidence for the highest levels of Roman material culture and architectural ambition in the province.
