Localties Database

These sites are, to the best of my knowledge, open and accessible. However, it may have been years since I last visited some of these locations. Be aware that ownership may have changed, there might be a new housing development on top of the site, or it may have sunk like Atlantis.

In other words, use common sense and don't trespass if the site is closed. If you do find a site that is no longer open, I'd appreciate it if you let me know, so I can relay that information to my other readers.
