An archaeological watching brief was undertaken on behalf of CgMs Consulting at St Martin's Gate, Worcester, Worcestershire (NGR ref SO 85287 55008; HER ref WCM102107). A single trench was excavated. Demolition material probably associated with the destruction of the suburb during the Civil War in 1651 was recovered from the lowest observed deposits. There followed a series of accumulated layers deriving from the redevelopment of the area into the early 19th century, either from cultivation or backyard plots. A large north to south ditch was dug through these layers, possibly as a plot delineation. This was backfilled with demolition rubble, likely to be from associated buildings fronting St Martin's Gate, prior to the construction of the Vinegar Works of Hill, Evans and Co in 1830.
