One of the best and cheapest (free) ways to see art is by going to a church. Even if you aren’t particularly religious you can still appreciate the beauty. The Saint Louis Basicila, in St. Louis, Missouri, is one of the most beautiful that I have ever seen. The entire inside of the building is covered in mosaics. All of the walls, ceilings, and floors just glitter. Each unique piece of glass, none bigger than a penny, reflect the light in the most mesmerizing way.
