Welcome to the Arms of Australia Inn Museum in the Penrith Valley at Emu Plains, NSW, Australia. The inn is administered by the Nepean District Historical Society (NDHS), and is situated at the gateway to the Blue Mountains National Park.
The inn was once a staging post for travellers making the trip from Sydney over the Blue Mountains to Bathurst and the goldfields. Built it two sections, the first in 1826, it is one of the oldest buildings in Penrith, if not the oldest.
Due to its colourful history, the inn provides an interesting venue for local activities, tour groups, special events, school tours and exhibitions. The museum contains artefacts that were either used or manufactured in the local area and thousands of photos.
