Nice set of shots! The Water Gate must have seen a few spring tides in its time!

The place reminds me of Bodiam Castle,[1] which we visited one summer's day some time ago; it was in much the same state of repair, and had lots of awkward, painful-to-negotiate steps too.

[1]We rode from Tenterden on the Kent and East Sussex Railway and walked to the castle from Bodiam Station, then newly-reopened. We had a pleasant lunch at the Castle Inn, which was close by.
