On our new year trip we decided to travel to France on a Dover crossing , for old time's sake. My parents used to live nearby for a time, so it used to be our preferred route in those days. I took the photo above as the ferry left the harbour. It shows Dover Castle on the cliffs above the town - the keep, the castle wall, and the Constable's Tower on the left.
The castle was a favourite haunt of our sons, and then it became a great place to visit with any of their friends who came to stay.

While I was looking up some information on the area I found the photo above on Wikipedia, which seems to have been taken from almost exactly the opposite direction to mine. It even has the ferry in the background!
This third view shows the castle church with the Roman lighthouse at the end of it. The arches half way down the cliff are part of the casemate barracks built between 1793 and 1801, and you are just able see an observation platform at the top of the cliff on the extreme right.
The cliffs are riddled with tunnels, some dating as far back as Tudor times and others from WWII. To the right of the casemate barracks are entrances to some tunnels which were converted to shelter the government if it became necessary. Some tunnels, but not the government shelter, are now open to the public.
