Excavations in Syon Park, Brentford, have made a substantial contribution to our knowledge of this Roman rural settlement on the London–Silchester road, by a ford across the Thames. The site yielded a well-dated sequence – from the mid 1st to early 5th century AD – including occupation deposits and two 2nd-century timber buildings destroyed by fire, as well as details of the main road and adjacent field system. These and a large assemblage of finds, including a surgical instrument and a roundel depicting the Medusa, provide a rare glimpse of life in the countryside in the hinterland of Londinium. A detailed overview of Roman Brentford (the first to be published since 1978) is included.
