Art Gallery of New South Wales is located at the northern end of Crescent Precinct Territory Park, Crescent District, east of Art Gallery Rd, south of the Royal Botanical Garden. Founded in 1874, the New South Wales Museum of Art is one of the three largest galleries in Australia. It is a collection of classical and modern fine arts from all over the world, including Australian art treasures from the 10th century to the 20th century, ancient European art and the works of Asian countries. The New South Wales Museum of Art is divided into five floors. It has rich collections, including Australian Art Department, Aboriginal Art Department, Asian Art Department, International Art Department, Contemporary Art Department and Photography Department. Every year, the three most important awards in Australian art circles are selected here, and the award-winning works are also exhibited here. The exterior walls of the gallery are all decorated with light orange stones. There is a prominent columnar at the entrance, which has the lingering charm of ancient Roman temples. The exterior facade runs through the narrow square windows between the upper and lower columns. The window frames and the lintels are typical Renaissance sculpture practices. Inside the entrance is a small porch-style exhibition room with a dome in the middle and a semicircle on both sides. Through this exhibition room, you can enter the main hall of the gallery. Unlike outdoor classical architecture, the floor of the gallery is light-colored marble, and there is no redundant decoration in the large exhibition hall. Paintings are hanging on the pink wall. A soft beam of light is emitted from the ceiling to provide suitable lighting for the painting. As the gallery is adjacent to the Royal Botanical Garden, architects open windows at the corner of some exhibition halls. Slender glass weakens the large interior entities, adds virtual and real changes, and introduces natural light to make the interior and exterior space interact. Besides enjoying the artworks, they can also enjoy the natural beauty of the outdoor. Time is tight. I stayed in the gallery for about 40 minutes and left. I will go again if I have the chance.
