Its rare to find a painting thats sufficiently weather-proof to hang on an exterior wall. So, youve got to find other ways to deck these spaces with art. Metal work is nice, and so are tile murals. But theres nothing like a fountain to add sound and motion to your outdoor décor. If you dont have the space for a large, freestanding pedestal style model, you can affix a fountain directly to a wall. Renaissance Rococo This first wall fountain is part of a complex arrangement of art. Its surrounded by several intricate examples of bas relief (not to be confused with the charitable organization for fresh water fish). The mosaic embellishment on the wall and fountain is done in a style called rocaille. Thats your new vocabulary word for the week, so see if you can work it into a conversation soon! The rocaille adornments are handmade by YardShare contributor Robert S. Thomas out of lava rock, marble, cut terra cotta tile, and shells. The fountain itself is a spigot and basin style that gives the whole area a historic feel.
