Nostra Signora del Sacro Rosario delle Betlemite is a dependent chapel of the parish of San Saturnino Martire , and is located at Via Lambro 12, in the Trieste quarter east of the southern edge of the Villa Ada.

It is the convent chapel of the Bethlehemite sisters (Figlie di Sacro Cuore Betlemite), who run a nursing home at the same address.

There is a two-storey neo-Romanesque façade topped by a triangular pediment. The first storey has three rectangular windows above the stone doorcase, and is decorated by horizontal sunken stripes. Above an architrave the second storey has three round-headed windows, and is bounded by a pair of Corinthian pilasters.
