Castle converted into flats

I took a trip to Kingsgate and Joss Bay yesterday, (in between Margate and Broadstairs)and walked along the beach contained by towering chalk cliffs and the enormous concrete, neo-classical sea defence propping up the Kingsgate castle, built in 1760 for Lord Holland.
It appears as though the concrete squares, on the sea defence wall, are blocking what were once windows? I can't see whatother purpose these concrete extrusions to the facade serve? The exterior walls of the castle are constructed entirely of flint.



The bay provides some of the largest sea formed chalk caves in the country. One even has an air or light shaft carved through the cliff to the surface. You can really appreciate why bays like these were notorious for smuggling.

Kingsgate castle has been converted into 31 flats with stunning views.

I recently learnt that English Heritage are struggling to make any profit on tourism at Dover Castle. Its an interesting thought if the Castle was to be converted into residential accommodation.
