Inspired by druids and ancient Briton, Camani has filled the castle and its grounds with fire-breathing dragons, arches shaped like gaping mouths, and an eerie forest of tree-shaped sculptures. The castle even has a dungeon. The most distinctive feature of the Midlothian Castle, however, are the hundreds of screaming concrete heads that he has placed throughout the grounds, including a giant one on top of a castle tower. In the words of the artist, Amidst the heads and disks, the solitude of the park envelopes the visitor in a peculiar silence, a silence both quieting and disquieting, penetrated only by the eerie scream of the peacock.
