OHNY this weekend!

Interested in architecture and design, or just want to get a free glimpse of some New York City sights and landmarks? See some subway tunnels or cruise the Brooklyn Navy Yard? Open House New York has a weekend event once a year, during which a bunch of sites throughout the five boroughs are open to the public (many of which are only open during this event). October 10 and 11 are the dates for this year.

This year the Lefferts Historic House is included, along with special events at the Brooklyn Public Library and Brooklyn Museum. (Reservations are required for tours of the Lefferts House.)

A PDF site listing is available here.
