Sandworm is a site-specific art installation and a fusion of environmental art and architecture by Finnish architect Marco Casagrande situated on the dunes of Wenduine beach in Belgium. The curvaceous structure is made entirely from willow. The fifty-metre long organic structure stretches out between the dunes like an enormous wooden worm. It is part of the Beaufort Triennial of Contemporary art.
The installation is an organic shell built from willow branches woven through arches of various heights placed at a length of 45 meters and a height and width of 10 meters. It falls within a local long tradition of willow weaving normally more modest in scale. Sandworm has been created in an undulating shape upon the tidal beaches of Wenduine town. From a distance, the mounds of tree remnants suggest the form of a massive creature, emerging out of the ground. Up close, visitors can investigate the textured surface of the structure, and they are invited to interact with the sculpture by walking through the interior. The space is used for picnics, relaxation and “post industrial meditation”.
