St Roque Church at Triq Sant' Ursula was designed by architect Mederico Blondel des Croisettes (a French military engineer & architect) as a centrally planned church with a dome over the crossing, having an apsed altar flanked by narrow sacristies, and two shallow transepts flanking the domed space. It was built in 1681.
Blondel's façade is less baroque and rather mannerist. The façade is made up of a balance between two slightly projecting wings of Corinthian pilasters. Each of the lateral wings is capped by a segmental pediment on each side of a plain raised bell-cot in the centre. The entrance is set within an apsed/concave niche with the door crowned by a broken segmental pediment, and a clerestory window above.
Mepa scheduled the Church of St Roque as a Grade 1 national monument as per Government Notice No. 276/08 in the Government Gazette dated March 28.
