This is where the original Declaration of Independence, Constitution, and Bill of Rights live. Stepping into the Rotunda for the Charters of Freedom, you’re literally standing in front of the documents that shaped this nation. Beyond the Rotunda, the museum has exhibits on American history and government that are easy to explore if you want to spend more time.

In addition to the Rotonda, this is one of the two most characteristic monuments in town. The Galerius arch is situated close to the eastern city wall, a short distance from the Kassandreotiki gate. The 4th-century AD Roman emperor Galerius commissioned both structures to show off his power. A road used to run through the arch, past the Rotunda and on to the palace to the southwest. The arch is composed of a masonry core faced with marble sculptural panels celebrating a victory over the seventh emperor in the Sassanid Persian Empire. About two-thirds of the arch is preserved. Colloquially, the monument in known as Kamara, that's Greek for 'arch'.

Rolling hills, national parks and state forests surround gorgeous Dungog. Its main street is an urban conservation area. Notable historic buildings include the primary school built in 1843 and designed by colonial architect Edmund Blacket, who also designed the University of Sydney and St Andrew's Cathedral in Sydney. The Dungog Cinema has a Spanish mission-style façade and is the oldest operating purpose-built cinema in Australia.
