Located in bustling Circular Quay, historic Customs House stands on the spot where modern Australia was founded. This is the site where the famous First Fleet came ashore in 1788, to establish a British penal colony in a land very far away. When the building was constructed in 1845, it was built in a classically Georgian style that’s exceptionally well preserved today, and simply the exterior is a sight in itself in the middle of Circular Quay. All the way up until 1990, Customs House served as the Customs Service headquarters for anyone entering the country, but today is a popular public space for just lounging and killing some time. On the top story, a café looks out over Circular Quay and is a nice place for grabbing a coffee, while the Sydney Library and it’s 400,000 books are open for viewing below. There’s free wi fi throughout the building—which is somewhat of a rarity in Sydney—and there’s even a miniature replica of the city in a glass atrium in the floor.
