Many thanks Local Hiker.
This is a place I have visited numerous times and often wondered about the circular building, though the lighthouses of Dungeness are a series of 'low-lights' and high-lights ranging from at least the early 1600's. From what I have gathered, it is the present lighthouse that dates from 1904 with the circular building adjacent being created in the 1860's from the two lower storeys of buildings that originally encircled the earlier 1792 lighthouse. Following the removal of the earlier lighthouse an open circular courtyard was formed in the buildings centre, which was subsequently capped by a glazed roof.
Here is my next offering, but who and where are this illustrious couple buried?
