Open House New York weekend may have come and gone, but that doesn't mean your only shot at seeing some of the city's secret spaces is lost and gone for another year entirely. OHNY is currently running a raffle for the chance to win a private behind-the-scenes tour of the Woolworth Building in the Financial District, one of the oldest and most gorgeously designed skyscrapers in the city. more ›

This weekend, Open House New York threw open the doors to hundreds of the city's most fascinating, normally-off-limits historical sites. Despite some pre-OHNY weekend website snafus, most sites opened their doors without a hitch (though not without crowds). We stopped by the Little Red Lighthouse in Fort Washington Park to get a nautical view of the city—here's what we saw. more ›

Last week, the full lineup for this year's Open House New York weekend was announced, and while dozens of amazing off-limits spaces are already opening their doors, there's always room for a few more, like the retro-fabulous TWA terminal at JFK Airport. more ›

This morning, the reservation line for for this year's Open House New York weekend on October 15-16 opened for business (complete with a new $5 booking fee). And, as some of you may have noticed, OHNY's website was a mess this morning—crashing, freezing and otherwise being totally useless, with many of the weekend's most popular sites "selling out" before people could even log on. Are we trying to tour a sewage treatment plant or score Radiohead tickets?! We spoke to OHNY officials about the snafu, and here's the latest: more ›

There are so many Open House New York sites open this weekend, and so little time to see them all! So we picked two that seemed interesting: this MTA powerstation on 53rd Street (built in 1901 by Heins & Lafarge, with help from McKim, Mead and White,) and the Newtown Creek Water Treatment Plant (which we'll tour tomorrow morning.) We need your help to visit the rest: please send your on-location pictures to photos@gothamist.com or tag them "gothamist" on Flickr, and we'll put up a gallery tomorrow night. more ›

It's that time of year again, to sneak into those off-limits nooks of New York! Today Open House New York, a favorite annual event, has opened up advance reservations for some of this year's tours (though some are on a first come, first serve basis). Hopefully you didn't have your hopes up to see McCarren Park Pool, as that one's been mysteriously cancelled. For the rest, they instruct that "advance reservations for participation will be listed online and in the printed event guide. Please follow the RSVP email or phone instructions found within the site or program listing." You can also purchase a passport for the weekend (which will get you into non-reservation events), and tickets for the Launch Party, being held in the raw space of the Penthouse at One York in Tribeca, on October 3rd. View Saturday's tours here, and Sunday's here. Something to note: today's NY Times has a OHNY Weekend Event Guide. more ›
