Tilbury, RM18 7NR, Tel 01375 858489
The largest and best preserved example of 17th-century military engineering in England, commanding the Thames and showing the development of fortifications over the following 200 years. Exhibitions, the powder magazine and the bunker-like 'casemates' demonstrate how the fort protected London from seaborne attack - there's even a chance to fire an anti-aircraft gun.
