Welcome to the New York Architecture Diary, your essential guide to architecture exhibitions and events taking place across the city.
From the nation's first public Christmas tree in Madison Square Park to the first written mention of St. Nicholas, many of our modern-day holiday traditions can trace their roots to New York City. Join 6sqft senior editor Dana Schulz for a walk around the Flatiron and Gramercy neighborhoods to explore the local history of Christmas. Other stops will include Pete's Tavern, where O. Henry penned "The Gift of the Magi" and Rolf's German Restaurant, which boasts a display of 15,000 ornaments and 10,000 lights, and the Union Square Holiday Market. Cost: $30 / $20 Members
