Sant’Elena all’Esquilino is a 19th century convent chapel dependent on the parish of Sant'Eusebio all'Esquilino , and is located at Via Machiavelli 24 off the Via Merulana. Pictures of the church on Wikipedia Commons are here.
The dedication is to St Helen the Empress.
It was designed by Ettore Genuini, and was completed in a French Gothic style in 1899 as the convent chapel of the Franciscan Missionaries of Mary.
The exterior of the convent looks rather like an attempt at a Venetian town house, rendered in pinkish-grey. There are four storeys, with the entrance through a Gothic archway on the right hand side. The windows are Gothic lancets, in triplets or singly, except for the fourth storey which has a row of seven behind a pilaster colonnade. The entrance archway has an inscription dedicating the building in honour of St Helen, and above there is a pictorial tiled panel depicting the Adoration of the Blessed Sacrament.
The interior is a small but tall and vaulted single nave, with stained-glass windows and a little circular apse framed by a Gothic archway. The apse itself has six round pilasters with capitals, supporting a sketchy attempt at vaulting in the conch, and there is a fresco of St Helen between the central pair. The archway bears a Latin inscription in Gothic script: Et verbum caro factum est, et habitavit in nobis. This is a quotation from the prologue of the Gospel of St John, and translates “And the Word was made flesh, and lived among us”.
