Veakio Theater, Open-air theatre in Kastélla, Piraeus, Greece.

Veakio Theater is an open-air venue on Profitis Ilias hill in Kastella, situated approximately 87 meters above sea level. The site offers views of the Saronic Gulf and Athens waterfront and accommodates around 2000 spectators.

The theatre was built in 1969 under mayor Aristidis Skylitsis and named Skylitseio. It was inaugurated on 22 June 1969 in the presence of regent Georgios Zoitakis. In 1976 it was renamed Veakio in honour of the Piraeus-born actor Aimilios Veakis. In 1970 it hosted the Miss Europe pageant.

The stage has hosted major Greek and foreign theatre companies, internationally known laiko music groups and concerts by well-known artists. The 1970 Miss Europe beauty contest was held here, as the national audiovisual archive footage records. The theatre remains the focus of an active artistic scene in Piraeus.

The venue operates during warm weather seasons and is easily accessible via public transportation from central Piraeus and Athens. Visitors should note that seating is outdoors and access routes may vary depending on the scheduled event.

The Skylitseio opened on 22 June 1969 in the presence of Regent Georgios Zoitakis, as recorded by the National Audiovisual Archive. On 15 September 1970 the same stage hosted the Miss Europe 1970 beauty contest, also filmed for the archive.
