AMARYNTHOS, GREECE—Swissinfo reports that a team of Swiss researchers led by Karl Reber of the University of Lausanne has discovered the lost temple of Artemis at the foot of the Paleoekklisies hill, on the Greek island of Euboea. The site, identified with artifacts inscribed with the name “Arthemidos,” is located about six miles from the place where the temple was previously thought to have stood. Archaeologist Denis Knöpfler of the University of Neuchâtel found a key clue to the temple’s location in a nearby Byzantine church that had pieces of the temple’s Doric columns and blocks in its façade. So far, the foundations of the building’s portico and inner courtyard have been uncovered. The temple was the end point of an annual procession from the city of Eretrea and home to a festival in honor of the goddess of hunting.

If I'm not mistaken that's the last famous "lost" temple known only from the texts.
