The quarantine station was built in 1852. This site was chose because it was remote from Melbourne and only accessible by boat. There are around 50 heritage-listed buildings making up the complex.
There are five double-storeyed buildings like this in the complex. They were used as hospitals and admin buildings amongst other uses. They were built from local sandstone. We don’t have a lot of sandstone in Victoria. Bluestone is the most well-known stone.
