In 1884 the estate was sold to the Sisters of the Good Samaritan for use as a charitable refuge for women. The Sisters added the impressive St Magdalen's Chapel (1888), which is believed to be the work of Sheerin & Hennessy, an important firm of Sydney architects, who designed the Archbishop's Residence and St Patrick's College at Manly. The neo-Gothic style Chapel is of major cultural significance. It is now deconsecrated and has been restored as part of the Discovery Point redevelopment. Tempe House is now listed on the Register of the National Estate.
