In 1856, landscape architects Frederick Law Olmsted and Calvert Vaux transformed 843 acres of land into New York's most treasured public space. The park contains grassy meadows, wooded groves, and formal gardens; paths for running, strolling, horseback riding, and biking; playing fields; a small zoo; an ice-skating rink; a carousel; an outdoor theater; and numerous fountains and sculptures. Highlights include the ornate, three-tiered the Bethesda Fountain (Midpark at 72nd St. Transverse); the magnificent formal Conservatory Garden (Near 5th Ave. and E. 105th St., COST: Free, OPEN: Daily 8-dusk); the Friedsam Memorial Carousel (Midpark south of 65th St. Transverse, COST: $1.25, OPEN: Apr.-Nov., daily 10-dusk Dec.-Mar., weekends 10-4:30, weather permitting); the Shakespeare Garden; and Strawberry Fields, the memorial to John Lennon (W. Park Dr. and W. 72nd St.).
