Tusculum, Potts Point, Heritage site and former residence in Potts Point, Australia

Tusculum is a former residence at 1–3 Manning Street in Potts Point, built from 1831 to 1837 to a design by John Verge for Alexander Brodie Spark. The two-storey Georgian villa has a symmetrical facade, a central entrance, and classical detailing. It was later altered in 1836 for its first tenant, Bishop William Broughton.

The building was constructed between 1831 and 1837 following designs by architect John Verge for Scottish merchant Alexander Brodie Spark. It later became a residence and gathering place for an early Anglican leader in the region.

The name Tusculum comes from a town in the Alban Hills near Rome where wealthy Romans built villas, chosen by Alexander Brodie Spark, who also named his other property Tempe House after a classical place. As Bishop William Broughton's tenant from 1836 to 1851, the house hosted the Conference of Australasian Bishops in October 1850, and a garden with rose trees from England was established.

Tusculum stands at 1–3 Manning Street in Potts Point and is owned by the Historic Houses Trust of New South Wales, so it is not a public museum with regular opening hours. The house was built as a private villa and later served as offices, so visitors should arrange any access in advance rather than expect to walk in.

Spark named the villa after the Roman town in the Alban Hills where wealthy Romans, Cicero among them, built villas. His other property, Tempe House, also took a classical name, and his literary education may explain both choices.
