Attikon

Attikon is a open-air cinema sitting right on Papadiamanti Street in the heart of Skiathos Town — it's been running since 1962 and is famously the filming location for Mamma Mia!, so there's a fun little buzz to catching a movie here. Open May through September, it screens new titles each week under the stars, with the ticket desk open nightly from 19:00–22:00. You can even reserve seats up to two weeks in advance via message.
