Inside the grounds of the
castle are a lighthouse from
Roman times and a church from
Saxon times, as well as the
castle, which is Norman. There
are three layers of tunnels
dug into the white chalk
cliffs by the castle that date
from medieval times. The
tunnels have also been used in
more recent times - they were
used in Napoleonic times when
the English were expecting an
attack from France and were
also used in the Second World
War. One of the levels is open
to the public. These tunnels
are the ones that were used in
World War II as a
communication center. It was
from these tunnels that the
evacuation from Dunkirk was
directed by Admiral Ramsay.
