Propylaea (Acropolis of Athens)

The Propylaea was the monumental gateway to the Acropolis of Athens, and was one of several public works commissioned by the Athenian leader Pericles in order to rebuild the Acropolis a generation after the conclusion of the Persian Wars. Pericles appointed his friend Phidias as the supervisor and lead architect of this massive project, which Pericles allegedly financed with funds appropriated from the treasury of the Delian League. According to Plutarch, the Propylaea was designed by the architect Mnesikles, about whom nothing else is known. Construction began in 437 BC and was terminated in 432, when the building was still unfinished.
