Papastratio Swimming Pool of Piraeus, Indoor swimming stadium in Piraeus, Greece

The Papastratio, officially the Petros Kapagerov National Indoor Swimming Pool of Piraeus, is an indoor swimming venue in the Papastratos industrial district of Piraeus. It opened in 1970 and holds 700 spectators. It has two pools: a 50-metre main pool and a 21-metre small pool.

The facility opened in 1970 and became a central training location for Greek water sports athletes. It has developed into one of the country's premier venues for competitive swimming and athlete preparation.

The facility serves as a key training hub for swimmers and water sports athletes in the city. It hosts competitions and events that draw both participants and spectators who follow the local athletic traditions.

The facility features non-slip flooring and is equipped with stairs and elevators to accommodate different mobility needs. Visiting is best planned when no official competitions are scheduled, as these events may affect public access.

The pool is named after Petros Kapagerov, a Piraeus basketball official, not a swimmer. The venue also hosted the 1986 Greek Men's Water Polo Cup final between Glyfada and Vouliagmeni. Olympiacos has won two Champions Leagues (2015, 2022) and three European Super Cups (2015, 2021, 2022) playing here.
