An official Path Through History Site! In 1968, Donald Judd purchased 101 Spring Street, a 5-story cast-iron building designed by Nicholas Whyte and constructed in 1870. It was the first building Judd owned, and he had an intense appreciation for its architecture and for the surrounding SoHo neighborhood. As one of the founding sites in the program of Historic Artists' Homes and Studios for the National Trust for Historic Preservation, 101 Spring Street is the only intact, single-use cast-iron building remaining in SoHo. This distinction has earned it the highest designation for national significance as part of the SoHo Historic Cast-Iron District. Guided visits offer visitors direct engagement with Donald Judd's art and vision. Judd's formerly private living and working space provides first-hand experience of Judd's concept of permanent installation in downtown New York.
