The Ancient Agora of Athens, also called the Classical Agora, is the ancient Greek marketplace and civic center of the city. It began as a place for trade, assembly and homes, and its remains show all three uses. It lies northwest of the Acropolis.

A visit is a slow walk through open ground with ruins on every side. The hill of the Areopagus bounds the site to the south, and Market Hill, Agoraios Kolonos, lies to the west. Plaka, with its labyrinthine streets and neoclassical buildings, lies nearby and is very popular with tourists.

• The visit means climbing the rock, and crowds are heavy most days.
• Spring and late autumn are the best times to visit Athens; winter is low season with fewer tourists.
• Summer can be extremely hot and dry during heatwaves, though this rarely happens.
• Peak traffic hours can be smoggy on main roads in Athens, which is enclosed by mountains in a basin.
