Charleston Manor is situated 0.6 miles NW of West Dean church (qv). The earliest datable feature in the W range is a late Norman window, set in the N wall at first-floor level, presumably to light a first-floor hall. An east range was added in the early 17thc. It was doubled by the erection of a new range along its north side in the late 18thc.

Probablyc.1180 (Datedc.1200 by Pevsner). The central capital, with its exposed bell, is a Transitional type. The waterleaf has prominent curling tips, but these are not quite crockets as yet. This might be 'Alured's Chapel, Charleston'? (see Sussex Archaeological Collections 1851, 47).
