Full description

A sallyport consisting of a stone walled and roofed passage with west inner side portcullis and extended steps, associated with the Elizabethan fortifications across the Garrison neck (7906.04), leads from the west side of Upper Benham battery (7906.13) to Lower Benham battery (7906.14). Two other sallyports (7906.06, 7906.07) and a gateway (7906.05) give access through the curtain the to north. This site is a Listed Building, Grade I and is Scheduled (h1). The feature is not recorded on the 1655, 1742 or 1834 plans (b1-b3). It is marked as 'sally port' on the 1888, 1907 and 1981 OS maps (b4-b6). The sallyport is mentioned by the OS fieldworker (h2) and was visited in 1988 (h3). In 1990 the west entrance portcullis slot and iron gate were found to be in good condition, and the offset hinges of the steps and the later rear wall of the Upper Benham battery noted (h4). The 1981 map shows the steps leading down to the curving passage beneath the SW corner of the Upper Benham battery (h5). The monument is included in the Schedule.

Found to be well preserved in 2005; the lower entrance opening onto a private garden (7).
