[3] To the west, the church has a tripartite façade, built in Massangis stone by the architect J. Rombaux in 1956, and supported by powerful buttresses with stepped slopes and saddlebacks.

[3] This façade is pierced in its centre by a classicist-style portal flanked on either side by flat, rounded pilasters whose Ionic capitals support an entablature comprising a high, undecorated architrave and a projecting cornice surmounted by a bas-relief sculpted by J. Lacroix in 1956 representing a Madonna and Child (Sedes Sapientiae) surrounded by two angels.

The portal is surmounted by an immense Gothic-style glass roof and a large gilded clock, carried by the gable.

To the west, the back of the church is occupied by an imposing rood screen supported by uncoated blue stone columns, each ending in a Corinthian capital.

[6] To the east, the choir, completely off-centre, has a central five-sided apse flanked by a single apsidiole on the left.
