A propylaea means an monumental gateway in ancient Greek architecture. Entrance into the Acropolis was controlled by the Propylaea. Though it was not built as a fortified structure, it was important that people not ritually clean be denied access to the sanctuary. It was one of several public works commissioned by the Athenian leader Pericles in order to rebuild the Acropolis hill at 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 Mnesicles, about whom nothing else is known. Construction began in 437 BC and was terminated in 432, when the building was still unfinished.
The Propylaea survived intact through the Greek, Roman and Byzantine periods. During the period of the Duchy of Athens, it served as the palace of the Acciaioli family, who ruled the duchy from 1388 to 1458. It was severely damaged by an explosion of a powder magazine in 1656, foreshadowing the even more grievous damage to the Parthenon from a similar cause in 1687. A Frankish tower, erected on the south wing, was pulled down in 1874.
The core is the central building, which presents a standard six-columned Doric façade both on the West to those entering the Acropolis and on the east to those departing. The columns echo the proportions of the columns of the Parthenon.
The Greek Revival Brandenburg Gate of Berlin and the Propylaea in Munich both evoke the central portion of the Athens propylaea.
References:The Jan Hus Memorial stands at one end of Old Town Square. The huge monument depicts victorious Hussite warriors and Protestants who were forced into exile 200 years after Hus, and a young mother who symbolises national rebirth. The monument was so large that the sculptor designed and built his own villa and studio where the work could be carried out. It was unveiled in 1915 to commemorate the 500th anniversary of Jan Hus' martyrdom. The memorial was designed by Ladislav Šaloun and paid for solely by public donations.
Born in 1369, Hus became an influential religious thinker, philosopher, and reformer in Prague. He was a key predecessor to the Protestant movement of the sixteenth century. In his works he criticized religious moral decay of the Catholic Church. Accordingly, the Czech patriot Hus believed that mass should be given in the vernacular, or local language, rather than in Latin. He was inspired by the teachings of John Wycliffe.
