With world-famous parks like the High Line and Central Park, smaller green spaces in New York City often get overlooked. But this summer, the small City Hall Park at the foot of the Brooklyn Bridge has become a destination for tourists and New Yorkers alike, thanks to the first ever outdoor retrospective of Sol LeWitt’s work. Put on by the Public Art Fund, “Sol LeWitt: Structures, 1965-2006” is a display of 27 pieces by LeWitt, placed strategically throughout the quiet outdoor space. The sculptures frame the green space, creating a fresh view of the historic park, transforming it into a temporary public art garden.
