Status: Turned into tourist attraction
Access to site: Yes (but there is an entry fee)

Upnor castle is older than all of the other forts (which were mainly built around the 1860s). Upnor castle is a Tudor fort built in 1559.

This site is now a tourist attraction. Apart from a few annoying musuemish signs, this place doesn't feel too much like its turned into a tourist place.
