Signalman's House [????-????]
I asked what the building on the right was in this c.1874 photo:
The 1874 list of Crown Property (Building) indicates that quarters were provided for staff (2 European signalmen and 2 Chinese assistants) at the Peak Signal Station. Perhaps the building on the right served the purpose of staff accommodation for signalmen from the Harbour Master's Office.
The building on the right was labelled by Annelisec as the "Signalman's House" (http://gwulo.com/atom/13100).
The photographer was on the highest point of the Peak when they took this. I've marked the approximate location on the map. I see there's a building on roughly the same site today. I wonder if any signs of the original building remain, eg the foundations?
