History's Best Worst Telescope

[Phil]

It is a little-known fact that "The Monument" in London, built by Sir Christopher Wren after the Great Fire, was intended by him to be a 200 ft vertical telescope. It was almost completed when astronomers pointed out that as it was not steerable, and very little of astronomical interest passes directly overhead in the UK, it would have been next to useless. Hastily replanning, and realizing that the base of the Tower was 212 ft from the starting point of the Fire, Wren added 12 feet of ironmongery to the top and renamed it The Monument.
