FREE Bring your budding architects to our LEGO Family Day where they can use problem-solving skills and imagination to make works of art and architecture at our LEGO building stations. Recreate some of our famous sculptures on display in the galleries, or invent your own new creations! Get inspired by the USPTO’s LEGO model of our historic building, which was home to the U.S. Patent Office in the nineteenth century. The model will remain on public view in our Luce Foundation Center through October 5.
