Werribee Park Mansion is an Italianate style mansion in Werribee, south-west of Melbourne.
Werribee Park Mansion was built between 1874 and 1877 by Scottish brothers Thomas and Andrew Chirnside. Thomas committed suicide in 1887. Andrew died three years later and the property was divided between his four sons.
In 1923, it was brought by the Catholic Church, who added additional wings, and it became Corpus Christi College, a Catholic seminary.
Currently it is owned by the Victorian Government. A separate wing housing the Mansion Hotel and Spa was later built.
It is free to explore the Werribee Park Mansion gardens and grounds, but entry to the Mansion is by admission.
One of the features of the 10 hectare grounds is an ornamental lake. A grotto is located on a man-made island in the middle of the lake. The grotto was built in 1877 and decorated by the Chirnside family. The ceiling is lined with shells from their holiday home at Point Cooke.
Werribee Park and Mansion is located at Gate 2, K Road, Werribee.
