| Summary: | Hand-tinted plan and sections of the main magazine for St Martin's Battery and the South Entrance Casemates at Western Heights and a site plan showing its location. There are notes detailing the commencement and completion dates for the building and its actual cost. The building was initially labelled St Martins Battery but this has been crossed out at a later date and South Entrance Gun Rooms written in. This is an extension to the casemates shown in MP/WST0056 and MP/WST0067 and may be the magazine built intentionally for St Martins Battery while they may show a magazine intended only for the South Entrance Gun Rooms. |
