The church is located in an urban context, fronted by a public roadway and encircled by small public space. The longitudinal plan features a central
nave and
transept, but departs from the traditional standards. The main face of the church is defined by a bell-tower and lateral extensions; rounded gables extend from the belltower/entrance facade topped with corners and pilasters decorated with
pinnacles. These extensions serve as lateral "entrances" to the public spaces, with their own rounded arches. The four-story, central body includes a portico and entablature with
jamb supporting a large window, crowned by
tympanum by João de Ruão. In Roman arch portico with square
soffits, is decorated with
rosettas and stars, delimited by pilasters and an entablature. The arch stands on a frame consisting of decorated pilasters and small columnar balustrades. Over the
archivolts are decorated
astragali, while flanking the door are pilasters divided by cornices with niches that contain the relief images of
Saint Peter and
Saint Paul (on either side), surmounted by urns. In bass relief are two profiles: on the left, a male figure, and on the right a female figure. The entablature, with sculpted
frieze, has the coat-of-arms of the Cantanhede family, while the on either extreme ends of the architrave are two decorative spires. Flanking the main entrance are two large grated, rectangular windows, midway between the door frame and surmounted window (in the center). While the base is interrupted by a staircase of two flights, of three steps (providing access to the main portico), the three subsequent registers extend above the main entrance. This central block (consisting of separate registers for the portico, window, bell-tower and clock) were constructed in the Renaissance-era style, and distinguishable from the younger elements. The belfry includes two rounded arches on the front and back facades, while single arches on lateral faces. Meanwhile, the clock face only appears on the front face of the tower, with lateral arch openings on either side.
Interior The three-nave interior includes five frames, with the first shorter than the rest, while a polygonal
presbytery is connected directly to the
sacristy. Roman arcades are supported by columnar drums fitted to the base with
Ionic capitals. In the last frame the columns encounter the eastern wall and jambs of the triumphal arch, in simple motif, whose blocks are carved in grotesque motifs, and extend to the level the drums and capitals. On top of the lateral naves, are two square-framed
aedicules carved from columns. The five-faceted, polygonal presbytery is covered in vaulted cross-shaped ceiling, forming a
Greek cross with sharp edges, rosettas and the coat-of-arms of the Cantanhede family. In the first frame of the lateral walls are two narrow windows with rounded frame. On the left wall is the embedded mausoleum of Cardinal D. José Manuel, who was the second patriarch of Lisbon, and family member of the Counts of Atalaia. The walls of the lateral naves are decorated along the footer by sillar azulejo tiles in blue and white. Over these are pattern azulejo in blue and yellow, with scenes from the New Testament and life of the saints. In addition, there are azulejo panels with the scenes from the Old Testament that decorate the sections of the central nave. Over the triumphal arch is another azulejo panel in blue and yellow, with the dove of the Holy Spirit. Over corbels, on the presbytery wall, is an image of the Virgin. Abutting the fourth column of the lateral nave, is the pulpit with wooden balustrades and stone base. One of the better known artifacts in the church is a
vermeil chalice dating to the 16th century and an armoire to guard the holy oils. ==References==
