Santi Martino e Sebastiano degli Svizzeri

The Church of Saints Martin and Sebastian of the Swiss (Santi Martino e Sebastiano degli Svizzeri) is a Roman Catholic oratory in Vatican City. The church was built by Pope Pius V in 1568 to serve as a private chapel for the Pontifical Swiss Guards, whose barracks are located next to Porta San Pellegrino, close to the Apostolic Palace. It is considered the national church of Switzerland in Rome. The chapel is conveniently located on the path taken every day by the Guards from their barracks to Portone di Bronzo. It is accessible for the guards, day and night. Baptisms and marriages of members of the Guard can also be celebrated with the permission of the priest of the parish of Saint Anne in Vatican.
