As the national capital, Canberra is home to the nation’s best public collections of art and culture. The National Museum of Australia presents the art, culture, and history of the nation in innovative and interactive exhibits that group works by concept, such as the history of travel, aboriginal Australians, or headdresses and masks. A huge collection of Australian and foreign art is on display at the National Gallery of Australia – its collections of Aboriginal and Torres Strait Islander art is especially impressive. The National Portrait Gallery displays more than 400 portraits of people who have influenced the growth and culture of Australia, represented in various media. Architecture buffs should visit the National Capital Exhibition in Commonwealth Park, which includes a model of the original Burley Griffin Plan for Canberra and an exhibit on how the city was built. It also offers great views over Lake Burley Griffin.
