In The Acropolis in Athens - a symbol in Greece, Jakob Jelling looks at the major monuments of ancient Greece still visible on the "Sacred Rock," the Parthenon ("built almost entirely with Pentelic marble and shows 8 columns at its two shorter sides and 17 columns at its longer ones"), the Temple of Athena Nike ( whose "walls contains depictures of gods' conferences and battles at each side"), the Propylaea (built following a design of the architect Mnesikles), and the Erechtheion (dedicated to Athena and Poseidon) all built between 450 and 330 B.C. In the same publication, Jelling looks at the Piraeus - The Port of Ancient Athens.
