The Art Gallery of South Australia (AGSA), located on the cultural boulevard of North Terrace in Adelaide, is the premier visual arts museum in the Australian state of South Australia. It has, after the National Gallery of Victoria, the largest state art collection in Australia.

With a large collection of more than 35,000 works of art and more than 510,000 visitors annually, the AGSA is renowned for its leading collections of Australian art (notablyIndigenous Australian and colonial art), British art (including a large collection by Morris & Co.) and Japanese art.

Located adjacent to State Library of South Australia, the South Australian Museum and the University of Adelaide, AGSA is part of Adelaide's North Terrace cultural precinct.

The Gallery was established in 1881, and has existed at its current location since 1900. Subsequent renovations and a significant extension of the building which opened in 1996 added contemporary display space without compromising the interior of the original Victorian building.

It was known as the National Gallery of South Australia until 1967 when the current name was adopted.

46. Arlington Antebellum Home and Gardens ( Alabama , USA )

The home is a perfectly-preserved emblem of Southern heritage. Staff are well-versed in how the home, which is older than the city itself, has been involved in many pivotal points of Birmingham's development. It's an interesting and inexpensive way to learn of the city's heritage, the civil rights struggle, and more. Be advised the home, on Birmingham's West End, is in a somewhat blighted neighborhood. However, visiting during daylight hours carries very little risk. And the home is accessible through main artery roads off of Interstate 65 at the Green Springs Avenue exit. Homeowners on the street adjacent to Arlington have well-manicured properties, symbolic of efforts by West End leaders to strengthen this historic part of town.

Arenal Volcano National Park is a Costa Rican national park in the central part of the country, forming the Arenal Tilaran Conservation Area. The park encompasses the Arenal Volcano, the most active in the country, which had previously been believed to be dormant until a major eruption in 1968. It neighbours Lake Arenal, which is the site of the country's largest hydroelectricity project, the Lake Arenal Dam.

The park also contains a second volcano, Chato, whose crater contains a lagoon. It is also called Cerro Chato (literally Mount Chato) as it has been inactive for around 3500 years–coinciding with the creation and growth of Arenal itself. The site has accommodation in the form of the Arenal Observatory Lodge and also the Museum of Vulcanicity, as well as a ranger station.

The park lies within the 2,040 square kilometres (790 sq mi) Arenal Tilaran Conservation Area, protecting eight of Costa Rica's 12 life zones and 16 protected reserves in the region between the Guanacaste and Tilarán mountain ranges, and including Lake Arenal. The park is most directly accessed from La Fortuna, but is also easily accessed via Tilarán and the north shore of Lake Arenal.

41. Arc de Triomphe ( France )

The Arc de Triomphe (Arc de Triomphe de l'Étoile) is one of the most famous monuments in Paris. It stands in the centre of the Place Charles de Gaulle (originally named Place de l'Étoile), at the western end of the Champs-Élysées. There is a smaller arch, the Arc de Triomphe du Carrousel, which stands west of the Louvre. The Arc de Triomphe (in English: "Triumphal Arch") honours those who fought and died for France in the French Revolutionary and the Napoleonic Wars, with the names of all French victories and generals inscribed on its inner and outer surfaces. Beneath its vault lies the Tomb of the Unknown Soldier from World War I.

The Arc de Triomphe is the linchpin of the historic axis (Axe historique) – a sequence of monuments and grand thoroughfares on a route which goes from the courtyard of the Louvre, to the Grande Arche de la Défense. The monument was designed by Jean Chalgrin in 1806, and its iconographic program pitted heroically nude French youths against bearded Germanic warriors in chain mail. It set the tone for public monuments, with triumphant patriotic messages.

The monument stands 50 metres (164 ft) in height, 45 m (148 ft) wide and 22 m (72 ft) deep. The large vault is 29.19 m (95.8 ft) high and 14.62 m (48.0 ft) wide. The small vault is 18.68 m (61.3 ft) high and 8.44 m (27.7 ft) wide. It was the largest triumphal arch in existence until the construction of the Arch of Triumph in Pyongyang, in 1982. Its design was inspired by the Roman Arch of Titus. The Arc de Triompheis so colossal that three weeks after the Paris victory parade in 1919, (marking the end of hostilities in World War I), Charles Godefroy flew his Nieuport biplane through it, with the event captured on newsreel.
