Foundations of buildings can be hard to understand and the Ministry of Works labelled individual buildings and features for visitors. This sign is placed on the east side of the ‘Commandant’s House’ at Chesters Roman Fort on Hadrian’s Wall (Northumberland).
Professor Eric Birley’s guide (Chesters Roman Fort, Ministry of Public Buildings and Works, 1960; sixth impression 1970) has a section on the ‘Commandant’s House and bath-house’ (p. 21). The building was excavated by John Clayton in 1843. The same terminology is also used on the fort plan.
Nick Hodgson’s guide (Chesters Roman Fort, English Heritage, 2011) has a section on the ‘Commanding officer’s house (Praetorium)’ (no. 4) and ‘Praetorium baths’ (no. 5). Indeed the sign ‘Commandant’s House’ is placed on what Hodgson defines as the ‘Praetorium baths’.
My 13th edition of Collingwood Bruce’s Handbook to the Roman Wall (1978) [ed. Charles Daniels] identifies the ‘House and baths of commandant’ (on the plan) but discusses ‘the commanding-officer’s house’ and ‘the commanding-officers’ [sic.] bath-house’ (p. 115). My 14th edition (2006; David J. Breeze) refers to the ‘commanding officer’s house’ (p. 203).
