The Borderline Festival is the Onassis Foundation’s annual electronic music festival — the Onassis Stegi’s longest-running — held at Onassis Ready in Agios Ioannis Rentis, Athens. Onassis Ready is a former industrial factory at 2 Strati Tsirka converted into a performance venue. The 16th edition is scheduled for early April 2027. The festival runs across two stages: a ground-level art soundscape above a basement club.
The 14th edition ran on 11 and 12 April 2025, with Donato Dozzy, Joy Orbison, and Moritz von Oswald, and Takis kinetic sculptures from the Onassis Collection installed through the venue. The 15th edition ran on 3 and 4 April 2026, with 25 artists across the two stages, led by Jeff Mills and J Spaceman of Spiritualized. The Foundation publishes each year’s full line-up and ticketing through the winter; the 2027 dates will be confirmed when the programme is announced.
