In Westerly you will find Wilcox Park, a grand space designed in 1898 by a protégé of Frederick Law Olmsted, the Central Park visionary. In it you may recognize the familiar choreography of walkways, ponds, and fountains. Wilcox’s 14-acre park-arboretum is on the National Register of Historic Places, along with its surrounding neighborhood. The park is delightful, notes Emmanuil Grinshpun.
