The Assassin (TV series, 2025) was primarily filmed in Greece. Key filming locations include Athens, with notable sites such as Zappeion Hall, the Parthenon, the Acropolis of Athens, and Salamis Island. These locations provided a magnificent and historically rich backdrop for the series. The filming started in August 2024 and included diverse settings like yachts, mansions, and woods around Athens to represent different countries and scenes in the story. The older parts of Greece were used to recreate Mediterranean island villages, as well as other international settings like Libya, Bulgaria, and Spain.
