There are a lot of net red subway stations in the world, attracting tourists to check in, but so far, no subway can be as unique as the Stockholm subway. There are three main lines, 100 stations, and the most special, it is the world's longest underground art gallery. Because of this, I even want to live in Stockholm, go to a subway station every day, and spend three months to finish. When Stockholm began to build the subway in 1950, people conceived how to decorate each subway station, and later decided to let more than 100 artists use their own style and artistic ideas to decorate a platform. So one of the world's longest subway networks has become one of the world's longest art galleries. In more than 100 subway stations, people can enjoy a variety of styles of painting, murals, sculptures and a variety of artistic expression techniques. Its wonderful.
