Lifestyle Beach art: Calvin Seibert builds modernist sandcastles on New York beaches By CARLA SINCLAIR/Special to amNewYork July 20, 2015 4:51 PM Print Share fbShare Tweet Email Every summer for the past fifty years, Calvin Seibert has been building sandcastles. But in recent years, the 57-year-old's sandcastles, built on New York beaches, have gained recognition online for their elaborate geometric "architectural" designs, which Seibert says can take up to two 10-hour days to build. "I rarely start with a plan, just a vague notion of trying to do something different each time," he writes on his Flickr, where he regularly posts images of the sandcastles. "In my mind they are always mash-ups of influences and ideas. I see a castle, a fishing village, a modernist sculpture, a stage set for the oscars all at once." In an phone interview on Saturday, Seibert said it was that "potential," that sets the medium apart and what "makes a sandcastle that much more interesting than just some sculpture in a plaza." On a more philosophical level, he said his fascination lies in the transient nature of the structures. "We're all doomed, but there's a different time frame for the sandcastles than you or I, hopefully," he said. "And that's what makes them interesting."

"They were deemed a hazard for the night time patrols." Photo Credit: Calvin Seibert "If a sandcastle can't be left to the elements then its really not a sandcastle," Seibert said on Flickr.
