Celebrate Diwali, the Indian festival of lights, at the South Street Seaport Museum and on Seaport Square. Diwali is a Hindu festival of lights. Come aboard the Seaport Museum’s 1885 tall ship Wavertree, where you can make your own decoration inspired by the marigold garlands of Diwali, signifying good fortune and faith in the divine, with a maritime twist. Continue the Seaport Museum’s festivities on Pier 16, where you can decorate your own “diya lamp”—or, in this case, a candle—and then set it afloat in a specially prepared pool to symbolize prosperity in the new year.
