Peace Tree at the Cathedral Church of St. John the Divine Tree Lighting

As it has for nearly 30 years, the colossal cathedral decorates its 20-foot tree with about 500 paper cranes (in Asia a symbol of harmony, longevity and reconciliation). The tradition was inspired by 11-year-old Hiroshima survivor Sadako Sasaki, immortalized in the book Sadako and the Thousand Paper Cranes, who succumbed to radiation-related cancer before she could finish folding 1,000 origami cranes. On view through Thu Jan 6. All ages.
