The hot and arid climate has dictated a lot of the fashion trends in Australia, and due to the sun's intense rays, hats are often worn by Australians. School children are required to wear sunhats as part of their school uniform, but they are also worn by adults.
The Potala Palace in Lhasa, Tibet, with 1000 rooms on 13 levels, and over 130,000 square meters of floor space, is one of the largest palaces in the world by floor area. It was the winter residence of the Dalai Lama until 1959. (Many sources, e.g. give the area as 360,000 square meters.)
The world's largest royal palace by floor space is the Royal Palace of Madrid in Spain, with 135,000 square metres (1,450,000 sq ft) of floorspace and contains 3,418 rooms. The world's largest palace by volume would be the Royal Palace of Caserta, with more than 2 million cubic meters (70 million cubic feet). The title of world's largest royal domain, as measured by the total area of the property, goes to the Palace of Versailles. Versailles's grounds cover 87,728,720 square feet (8,150,265 m2), or 2,014 acres, including 230 acres of gardens.
