On reading accounts of Kwun Chung Fort, it's placement was said to be within the boundaries of Jordan Rd. to the north and Austin Rd. to the south on a ridge.
When I lived in this area in the nineteen fifties, that ridge, which I think was a northerly extension off Observatory hill ( Mt. Elgin?) was still apparent, running betweenTak Hing St. and Cox's Rd. Nearly all the buildings ( Flats, schools, Norwegian Missions to Seamen and Cox's Path terraced houses ( now part of Carmen's Gardens) were elevated above street level and terminated in a high cut-away behind Union Church on Jordan Rd.
The highest point was The Norwegian Missions to Seamen which was directly across the road from the K.C.C. Clubhouse on Cox's Rd.
It would be interesting to know precisely where that old fort was. From what I've read it says that the British demolished the fort with hill for development.
And what of the Tsim sha Tsui Fort. Would that have been on Signal Hill or the site of the old Marine Police Station?
Would like to know more.
