When did the last of the High Elves leave Middle Earth ?

For me, the implication clearly seems to be that Círdan was on board the ship which took the Keepers of the Three, and that the remaining High Elves also went at that time.
Círdan's absence also would explain why Legolas built a ship for himself and Gimli in Ithilien.

I don't agree that Cirdan left with the Keepers of the Three. In the Appendices of ROTK there's a statement somewhere about the Havens, where it's said in relation to Cirdan that "some say he dwells there still, until the last ship sails".
