Archtober truly began in 2003 when the American Institute of Architects New York (AIANY) opened the Center for Architecture and openhousenewyork (OHNY) opened our city to architecture aficionados, the general public, and visitors from around the world. For the next seven years, Architecture Week took place in the second week of October concluded with the Annual OHNY Weekend. In 2010, the Architecture & Design Film Festival hosted its first New York event the following week.
These events inspired Architecture Week to grow into a month-long celebration, Archtober, which launched in 2011 and now includes a larger collective of local architecture and design organizations to further emphasize and promote the importance of architecture and design in New York City. One highlight is Building of the Day, the Center for Architecture's daily tours of notable buildings led by architects and other design professionals, which include contemporary buildings and historic sites. Many events are free; individual pricing and ticketing information is available on each organization’s website.
