Heritage Value

The Convent of Our Lady of Mercy has been designated a Registered Heritage Structure by the Heritage Foundation of Newfoundland and Labrador due to its historic and aesthetic value.

The Convent of Our Lady of Mercy was built in 1857 under the supervision of Rt. Rev. Mullock. It was built to replace an earlier wooden convent, constructed in 1842 and situated approximately where the chapel now stands. The Oratory of the Sacred Heart chapel was built in 1892 as a memorial to the Golden Jubilee. The room that served as a chapel since 1857 became the present community room. The Sisters of Mercy are a Roman Catholic order of nuns that started their work in Newfoundland in 1842. The Order was founded in Dublin in 1831 by Sister Catherine McAuley. In 1841, Bishop Fleming decided to establish a convent and day school for families that were capable of paying educational fees. This institution would complement the existing school and convent for the poor operated by the Presentation Sisters. The Sisters of Mercy were commissioned by Bishop Fleming to accomplish this task. The Sisters of Mercy have made an important contribution to St. John’s through their work in various fields. They are known for their work in health care at St. Clare’s Mercy Hospital, their work with the elderly at St. Patrick’s Mercy Home and their work in education. The Convent of Our Lady of Mercy is historically valuable as a symbol of the work of the Sisters of Mercy in Newfoundland.

The Convent of Our Lady of Mercy is architecturally valuable as an example of the Second Empire style employed in an institutional building. Many of the typical Second Empire elements are preserved in this building including peaked dormers, a mansard roof, and eaves brackets. Furthermore, an interesting feature of the building is an M-shaped red stone on the west wall of the building. Bishop Mullock received the stone from the Motherhouse of the Carmelite Sisters in Spain. The stone was meant to link The Convent of Our Lady of Mercy with Bishop Mullock’s alma mater, the Carmelite University of Salamanca.

The Oratory of the Sacred Heart chapel is architecturally valuable as a fine example of Renaissance Revival architecture in an ecclesiastical context. Constructed of granite, the Oratory of the Sacred Heart features rusticated quoining on the exterior and has large stained glass windows. The front façade of the chapel features a large stained glass window, and a large entranceway with decorative trim. The main entrance is flanked by a small turret on each side with a statue of the Sacred Heart in the centre. It has a gambrel roof and a rounded apse with a domed ceiling at the east end. The chapel has a well-preserved interior that features many elements of the Renaissance Revival style, including a domed ceiling over the altar, elaborate plasterwork and trim painted in bright colors. There are also decorative pilasters with Corinthian capitals and intricate stained glass windows throughout the chapel.

The Convent of Our Lady of Mercy has further aesthetic value due to its environmental setting. The Convent of Our Lady of Mercy is located on Military Road near the Basilica of St. John the Baptist and Presentation Convent. Furthermore, it is one of a larger complex of ecclesiastical buildings in this area of St. John’s.
