Although the site is now a jumble of monuments and ruins from different periods, in Athens' heyday, the Agorá was the focus of city life, serving not only as a place of trade but also as the city's political, administrative and cultural heart. Law courts, temples and public offices were all based in this area, where ordinary Athenians, stall holders and merchants mingled with officials, politicians and philosophers. The site is dominated by the fifth-century BC Hephaisteion (Temple of Haephaistos), one of the best-preserved ancient temples in Greece. The fascinating Museo tis Agoras (Museum of Agorá) contains an eccentric array of everyday artefacts found in the area. It is housed in the second-century BC Stoa Attalou (Stoa of Attalos), which is thought to have been an early shopping arcade containing 42 separate shops.
