Open House New York Weekend is an annual festival that unlocks 300+ destinations across all five boroughs for behind-the-scenes tours and special activities. The ICAA is excited to participate in OHNY Weekend by opening our Cast Hall collection to the public on October 17 & 18, 2025. The Institute of Classical Architecture & Art's Cast Hall displays a collection of historical plaster casts of Classical and Renaissance architecture and sculpture alongside fragments of historical woodwork from significant buildings and country houses in the United Kingdom.The Cast Hall is a gem of 19th-century New York City's art collecting past. Filled with plaster casts originally owned by The Metropolitan Museum of Art, the gallery now plays host to scores of visitors, ranging from students to practicing artists. Visit the Cast Hall for open sketching and to learn about this historic art practice and collection.The Gallery Coordinator will be on site to give first-come, first-served gallery talks throughout each day to help visitors learn more about the historic collection. (Talks are 30 minutes each and begin at 11:30 AM, 1:30 PM, and 3:30 PM.) Art making for both adults and children will also be available throughout the duration.For more information about this program, please visit the Open House New York website.
