The equator line runs right through Quito, so naturally this is a huge tourist attraction.
Here is the "first" equator line, discovered and mapped by the French back in the 1700's or something like that. This is the more historical area.
Along with GPS technology came another, more exact equator line about 200 meters away. Of course, this is yet another tourist attraction.
This is a sun clock, but as it is sitting exactly on the equator, it is the only one of it's kind that can be vertical rather than horizontal. This may be interesting to any math freaks but probably no one else...
