Report on a programme of archaeological monitoring and recording conducted during groundworks for a new water pipe on land to the south of Lion Lodge, in the grounds of Belton House. A substantial foundation of dressed limestone blocks was encountered on the line of the track, approximitely 50m to the south of, and closely aligned to, the current location of the Hall's south gate. The foundation measured at least 5.5m wide, and projected beyond the edge of the track on both sides. To the east of the foundation was a 1.05m long surface of limestone slabs. Overlying both the foundation and surface was a substantial demolition deposit containing loose mortar and limestone chunks, as well as fragments of brick and pantile of 18th-19th century date. A single potsherd of similar date was recovered from this deposit. Lion Lodge was said to have originally been built to the south of the gate in the approximate location of the foundation, and this may also account for the demolition deposit.
