This modern cultural landmark covers an entire block of Syngrou Avenue. Architecture Studio’s bold design is a glass cube cloaked in rows of white marble that glow at night. Known locally as Stegi (Roof), the building hosts theatre, dance, and musical performances by Greek and leading international artists, as well as boundary-pushing exhibitions that often extend off-site. The top-floor bar and restaurant, Hytra, is a destination in its own right.
