<p>The church of Our Lady of the Rosary is one of the oldest preserved buildings in Goa. Its primary entrance in the west and it lies on a east-west axis. It is situated on a cliff overlooking the Mandovi River on its south bank, a short distance to the west from the Basilica of Bom Jesus and the Se Cathedral.</p><p>The facade of the church has three floors and a two-storied portico flanked by cylindrical buttresses and cylindrical towers, each tower with cupolas crowned with crosses. The high windows, near the roof, give the impression of a fortress church with a cruciform plan.</p><p>Indian design elements are visible on the facade. Large cords are located at the cornice as well as the individual towers. The southern tower has a turning staircase to get to the upper choir on the second floor of the tower‑facade and the rood screen. The church's baptismal font is located on the ground floor of the northern tower. On the highest floor of the tower façade, there are light graceful columns in the corners, with window openings on all sides, and suspended bells.</p><p>The church has two chapels and one nave with a main altar and two side altars. The main altar is dedicated to Our Lady of Rosary. Surviving tile fragments bear witness to the once ornate nature of the altar. The nave now has a partly open roof, after parts of the roof collapsed in 1897. The side chapels and the altar are arranged by a leaf-vein vault in the shape of a star, with decorative relief medallions on the ceiling.</p><p>While the vault of the apse corresponds to the Gothic style, the main room of the church is largely Manueline style. The influence of Gothic style is seen in the rib vault of the Manueline style portico.</p>
