You will find the narrow area between Ermou Street and Adrianou Street, and the Monastiraki Metro Station and Thissio Metro Station (the junction of Apostolou Pavlou Street with Ermou Street). Hypothetically, of course, we say that it extends to Aiolou Street to the east and the Roman Agora to the south.
Monastiraki is the pleasure of the collector. On Ifaistou Street, there are tens of small shops selling furniture, appliances, clothes and shoes, as well as, beads, used records and small items of decoration.
Especially in the antique bazaar of Avissinias Square, the well-known Giousouroum, when you really look thoroughly, you may find a small treasure. That may be a telescope, a rare antique, a diving suite or a shiny saxophone, all in debatable prices, as it was done in Athens in bygone years. What one sees wandering in Monastiraki on Sunday morning, it is rare to see elsewhere. Crowds of people roam the pedestrian precincts, sometimes with the sole purpose of a stroll, in itself, with no particular destination.
