Royal Citadel 
Description
Built in 1666 to make it very clear to the republican people of Plymouth that the King was back in charge, today the citadel still houses army commandos, and consequently is only open to a couple of guided tours a week (check English Heritage website for details). On the tour you get to go around the ramparts of the citadel and into the chapel.
