The iconic wedding scenes in the first Mamma Mia! film were primarily filmed on the Greek island of Skopelos. The tiny, picturesque chapel where Sophie’s wedding takes place is the Agios Ioannis sto Kastri, perched atop a 100-meter rocky outcrop jutting into the Aegean Sea. To reach the chapel, visitors must climb roughly 200 steep steps carved into the stone. While the interior wedding shots were largely filmed on a soundstage at Pinewood Studios in the UK, the stunning exterior and the winding path where Meryl Streep sings "The Winner Takes It All" are authentic Skopelos landmarks. In 2026, the chapel remains one of the most popular pilgrimage sites in Greece for fans of the movie, offering breathtaking views of the turquoise waters below.
