Madonna dei Lumi is a 20th century public dependent chapel of the parish of Santi Simone e Giuda Taddeo a Torre Angela , and is located at Via Chirone 27 in the suburb of Torre Angela, south of the junction between the Via Prenestina and the Circonvallazione Orientale.
The little chapel is part of a sports and social complex, and is a unit in a larger one-storey building. It has absolutely no architectural interest. Look for a tiny rectangular frontage rendered in dull yellow, on top of a concrete revetment and behind a wire fence. There is a door on the left hand side, a square window to the right and a horizontal tiled canopy stretching the full width. That's it.
According to the DIocese (June 2018), the chapel is now closed in summer.
In winter, Mass is celebrated on Wednesdays at 17:30, and Sundays (and Solemnities) at 10:00.
