Four strange places to see London's Roman Wall

Not bad engineering to make it through a handful of civil wars, a Blitz, and a couple thousand V-1 rockets mostly intact. You have to wonder how long all the steel and concrete that's been laid around the Thames from our civilization will last.

There's a Templar fortress in Lebanon that was occupied by militants a few years ago. 800 years old and still being used for its intended purpose.

Most of the wall has been plundered for stone and to make way for new development over the past millennium. Its not conflict that has destroyed 2 miles of a 6m high 3m thick wall, it's peace :)

There is a Templar church in London off Fleet Street as well, and again, being used as intended.

Plus the crypt of St Bride's has a Roman pavement to look at. Nice and quiet down there.
