I watched a show that asked this question. The undisputed champ was ~~Hoover damn~~ Mt. Rushmore with an estimated expected life of hundreds of thousands of years.

EDIT: It was Mt Rushmore not Hoover Dam.

Hoover Dam is also expected to last a long time. The forces on the structure are mainly compression and it isn't a seismically active area. The big question is whether the electricity generating turbines would fail open or shut.

What about servicing those turbines so they don't fail at all? "This dam powers our city since 4000 years." Sounds nice and Star Trek-ish doesn't it?
