The world’s first underground park inched towards reality on Friday, when the Kickstarter campaign to realize the initial phases of the Delancey Underground (better known by its nickname, the LowLine) soared past its $100,000 target. That means its co-founders, designer James Ramsey of RAAD Studio and social entrepreneur Dan Barasch, can get to work on erecting a scale model of their mystical vision: an underground public space teeming with foliage and natural light housed in the 1.5-acre abandoned Williamsburg Trolley Terminal. Hoping to engage the city with their radical fantasy, Ramsey and Barasch took to the Mark Miller Gallery and organized Let There Be Light, an exhibition that lays bare the complexities of the ambitious endeavor.

The month-long exhibit features a life-size rendering and 3D model of the park, along with architectural renderings and images of the site at present. Most compelling are the initial design prototypes, sketches, and painstakingly detailed renderings, which flesh out the LowLine’s sophisticated use of solar technology. The plan calls for fiber optic cables and solar reflectors to transfer sunlight below the ground, creating a futuristic, greenhouse-like environment for farmers markets, concerts, and art installations year-round. Viewers are invited to bring along suggestions for the designers to incorporate into this subterranean paradise.
