Santa Maria Assunta delle Suore di San Giovanni Battista is a dependent chapel of the parish of Santa Maria del Rosario in Prati , and is located at Viale Giulio Cesare 116. It is the convent chapel of the Sisters of St John the Baptist, and is sometimes misnamed San Giovanni Battista ai Prati because of the name of the congregation. They have the nickname Battistine.
The rather severe neo-Romanesque façade features four Doric pilasters which rise from tall plinths either side of the door to the fractured segmental pediment, the central section of which is slightly set back. Their capitals break into the entablature. There is a tall round-headed lancet window between each pair of pilasters, and a horizontal oeil-de-boeuf window over the entrance and just under the entablature. The stone doorcase has a cornice superimposed, and over this is a half-moon window framed by two stubby pilasters supporting another projecting cornice. This, in its turn, supports a coat-of-arms.
