I spent yesterday being shown round the Western Heights, an amazing set of Napoleonic forts constructed on the hill west of Dover Castle, originally begun in the 1780s during the American War of Independence and then reinforced in the 1790s and again after 1803 when there were fears of a French invasion. One half, known as the Citadel, was converted into a Borstal after the Second World War and later into what is euphemistically called an Immigration Removal Centre of a type which will be familiar to those who watched the excellent television programmes about the Windrush Scandal.

The entrance, not very inviting:-

The Officers’ Mess:-

At the other end of the Western Heights is the Drop Redoubt, which is in the care of Historic England:-
