Take advantage of this December's unusually warm weather and head down to the Seaport Culture District (181 Front Street, NYC) with your little ones to see the boats and the holiday decor, as well as some of the city's oldest and most captivating architecture. The AIA New York Center for Architecture will hold their monthly Family Day on Saturday, December 12, 2015 from 11:00am-4:00pm. (Tickets are $20 for a family of four. Click here to register.) December's workshop explores the design of lighthouses. Children will learn about the important history of the Seaport's lighthouses and then have the opportunity to create one of their own, complete with a working light. Afterwards, don't miss the nearby Imagination Playground, one of the city's best, designed by renowned architect David Rockwell, with room to run, play, and problem solve, engaging both little bodies and minds.
