Estate of Elizabeth Bay is located in the Sydney suburb house with historical value. Built between 1835 and 1839 in the style of an English Empire, it was known as "the finest house in the colony". Once he was surrounded by the amazing beauty of the garden with an area of 22 hectares, however long ago instead of green plantings house Museum surrounded by a densely populated urban area. Today the estate of Elizabeth Bay is a wonderful example of Australian colonial architecture, is best known for its main oval hall with a domed lantern tower and staircase.

The estate was built for the Secretary of the colony of New South Wales Alexander Macleaya in the second quarter of the 19th century. The project architect is unknown – assume it could be John Virge, however, credible evidence that there is. The facade is quite simple due to the fact that the house itself is unfinished: the construction of most of the colonial houses of the late 1830s, was not completed due to the economic depression. Interestingly, the Central axis of the house is in line with the point of the winter solstice. Did not have any documents that could explain this feature, but it is unlikely a coincidence.

The interior of the mansion, restored by the record reflects the family's lifestyle Macleaya and generally gives an idea about the life of Sydney early 19th century. In the large library you can see a small collection of insects belonged to Alexander Maclay, - he was a famous entomologist. Here is the collection of 19th century furniture from Sydney and Tasmania.

Near the farmstead there is a small grotto with stone wall and steps surrounded by a few trees is all that remains of the once extensive garden, in which grew exotic plants from the collection of Macleaya were a greenhouse and a vegetable garden.
