Well-preserved, it was cleaned and repaired few years ago. It looks like new now and is one of the city's landmarks. It is probably of Roman origin but the present structure dates to the 16th century during Sultan Suleiman the Magnificent's repair and improvement of the Byzantine fortifications. It reaches up to 25 meters high, 280 m long and contains 60 arches. Interesting to see are also some old houses that were built into this monument. If you go 100 m up the street on the side of the new town (Hellenikis Dimokratias Str.) and turn right into the 2nd street (Konstantinidou Str) after 50m (in front of the school) you find the start of the Aqueduct. You can even climb on it a few meters to take nice photos of the Aqueduct plus Old Town.
