The Parthenon and Erechtheum are the most prominent buildings in the photo taken from the southeast. The small niche jutting north from the Erechtheum (toward the Parthenon) is the Porch of the Caryatids. Three columns of the eastern facade of the Propylaea (the entrance to the Acropolis) are visible just beyond and to the right of the Parthenon.
