Santa Maria Maddalena agli Arcacci is a 20th century dependent chapel of the parish of Santi Simone e Giuda Taddeo a Torre Angela , and is located at Via Trinitapoli 88 in the north part of the suburb of Torre Angela, near the junction of the Via Prenestina with the Grande Raccordo Anulare (Circonvallazione Orientale).
The dedication is to St Mary Magdalen.
It is a little, nondescript flat-roofed pale orange building behind a railing gate at the north-west end of the street, which is a dead end here. Look for the large cross perched on the right hand corner of the roof.
According to the Diocese (June 2018), the chapel is now closed during the week in summer.
Mass is celebrated on Wednesdays in winter at 16:30, and on Sundays and Solemnities at 9:00 and 11:00 (winter only).
