Seven Sentinels is a kinetic artwork and permanent public installation by Matt Dehaemers. Zahner provided engineering, art fabrication, installation for the public artwork, located in Kansas City, Missouri.
The installation consists of seven equidistant, elongated and oversized parking gates. These were manufactured several times the height of a standard parking gate. Each of the seven pieces were engineered to individually automatically open as a kinetic sculpture. As visitors exit the facility, each parking gate rises to salute drivers leaving the New Municipal Vehicle Impound Tow Lot Facility.
The parking gates were each crafted from powder-coated aluminum and galvanized steel. The sculptures react to incoming traffic, lifting their gates as cars pass underneath. The kinetic movement is a reference to soldiers performing a sword ceremony, and as such shows respect to vehicles exiting the lot. Seven Sentinels was completed in 2008. It is the first public artwork collaboration between Dehaemers and Zahner. Dehaemers’ second collaboration with Zahner, Catalyst, was completed in 2010 and stands at the intersection of 31st Street and Troost in Kansas City.
Each gate tower is 16 feet tall and the each gate is 12 feet long. The towers are placed 30 feet apart for a total of 180 feet from end to end. The artwork is made in galvanized steel, with powder-coated aluminum gate bars, parking control mechanisms, concrete, and a surface-mounted loop detector to trigger the artwork’s kinetic movement.
