The church of S.Salvatore de'Bireto is in the main square of Atrani (piazza Umberto I). It was restored, and modified several times in the neoclassic style, but the original structure was built in 940.

The main door of the church was made in Costantinopoli in 1087, and ordered by Pantaleone Viaretta, who also donated the main door of the Duomo of Amalfi 20 years earlier.

The church, S.Salvatore de'Bireto, was also used by the aristocracy of Amalfi for the elections of the "Dogi della Repubblica Amalfitana" . When a new Duke, or "Dogi", was elected, they were crowned with a typical pointed hat. Becoming a Duke was the highest position attainable in ancient Amalfitan society.
