The idea behind These Four Walls is for it to be a gallery with a semi-informal atmosphere where "average people" are able to purchase original works of art at affordable prices. What I like about the gallery is that their website's homepage has a link to photos of the works displayed in the current exhibition.
These Four Walls is at 169 Lower Main Road in Observatory, and is open Tuesday through Friday from 10h00 to 17h00, and Saturday from 10h00 to 13h00. Most artists don't paint to make money, they paint to express something for others to enjoy. So, if you find yourself in the area, if you love art, and even if you're not shopping, visit the gallery and stimulate your creativity.
