Expanding on the publication of the shipsheds and slipways found in the northern half of Group 1 (Area 1) on the eastern side of Zea Harbour in Volume I.1-2 (2011) of the Ancient Harbours of the Piraeus series, Volume II presents further results of the archaeological investigations conducted by the Zea Harbour Project (ZHP) in 2004-2010 and 2012 of ancient shipsheds and slipways in Zea Harbour (Pashalimani), both identified and possible, making them the best documented structures in Athens' naval bases and in the wider Mediterranean.
