Peace and Friendship Stadium, multi-purpose indoor arena that is located in Piraeus, on the coastal zone of Attica, Greece

Peace and Friendship Stadium (SEF) is an indoor arena in Neo Faliro, Piraeus, opposite Karaiskakis Stadium. It opened in 1985 with a design inspired by Palasport di San Siro, and its tiered blue seating rings a central court under a dark ceiling hung with club banners. The building also holds a 942-seat amphitheater and halls totalling 16,048 sqm.

The Peace and Friendship Stadium opened on 16 February 1985, built to a design by Thymios Papagiannis and Associates at a cost of €25,000,000 in 1983 prices, and hosted the European Athletics Indoor Championships that March. It was conceived as a dual-use hall with an Olympic-size 30 x 60 m ice rink under a special oak parquet floor, and the first Greek Ice Hockey Championship was held there in 1989. Closed from April 2002 to early 2004 for a €7,300,000 renovation, it hosted the 2004 Olympic indoor volleyball tournament; in July 2025 the Greek parliament approved a 49-year concession to Olympiacos.

The arena is the home court of Olympiacos basketball club, whose fans fill the stands for EuroLeague and Greek League games. Its name, Peace and Friendship Stadium, is shortened to SEF by locals. Outside sport, it has hosted concerts by Phil Collins, Dire Straits, Deep Purple and Placebo, and in November 1998 the rock band Termites played a reunion concert here before more than 25,000 people, released as a gold live album.

The venue is accessible by public transportation and offers parking for visitors. It is advisable to arrive early, especially during major events, to allow sufficient time for parking and finding your entrance.

The arena was built with a permanent 30 x 60 m Olympic-size ice rink, the only one of its kind in Greece, covered by a special oak parquet floor so it could switch back to ice at any time. It hosted the first Greek Ice Hockey Championship in 1989 and ice shows such as Holiday On Ice in 1996.
