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 ›

Every fall, the city flings open the doors to some of its most amazing, off-limits spaces for a weekend-long celebration known as Open House New York.

Open House New York has arrived! There are dozens of amazing locations open today and tomorrow in all five boroughs, so we're not going to be able to visit them all.

Open House New York (OHNY) is back for another year, opening usually closed doors to the public.

Over the weekend, we looked at just a few of the many OHNY sites: the Newtown Wastewater Treatment Plant, an MTA Substation, and the Brooklyn Navy Yard. Here's a gallery of some of our other favorites, submitted by Gothamist users. more ›

As part of our continuing Open House New York coverage, we visited the Newtown Creek Wastewater Treatment Plant this morning. It is enormous: dozens of buildings on 53 acres at the northern edge of Greenpoint. You've probably seen the huge silver digester eggs from the BQE— at night they're lit up with pretty blue light. An overview of what goes on there: "with a rated capacity of 1.2 million m³/d, this is New York City's largest wastewater pump station and serves an area of 4,162 acres of land, fed by 180 miles of sewers. " Polshek Partnership is responsible for the plant's design— check out their site for some cool progress pictures. more ›

Yesterday, the Brooklyn Navy Yard Development Corporation opened up its doors to bicyclists for Open House New York bike and bus tours. Here are just some of one reader's photographs from yesterday's tour of the shipbuilding yard-turned-industrial park (Steiner Studios is located there). 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 ›

This Saturday, as part of Open House NY, the Green-Wood Historic Fund and Dance Theatre Etcetera will bring Angels & Accordions to the cemetery. "A site-specific, live music and dance performance that guides audience members through historic Green-Wood Cemetery’s rolling hills, highlighting its unparalleled collection of sculpture and monuments." Looks like the 30 dancers involved have been doing some practicing! To check it out in real life, head over there tomorrow at noon or 3:30 p.m. 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 ›

A well-known ruin is crumbling. According to Roosevelt Island Historical Society president and historian Judith Berdy, part of the north wing of the Smallpox Hospital collapsed about a week ago. She writes, "The rest of the north wing especially the front is in danger of coming down any time... [The Roosevelt Island Operation Corporation] is working with TPL, the Southpoint park developers to find a way to do emergency stabilization of the rest of the building... Please encourage RIOC to do all possible to save the rest of the building." more ›

Of all the forbidden sites that were opened for public viewing last weekend in the 5th annual Open House New York program, the High Line was one of the crown trophies. It offered rare views of the city, sexy industrial details, and the mysterious allure of a wild grassy flying carpet that won't open until at least a year hence. Built during the same era (early 1930s) as the Empire State Building, the George Washington Bridge and other Gotham landmarks, could this elevated former freight railway become a comparably iconic amenity? more ›

October is starting off with a continuation of September's trend of quiet weather. Central Park was 2.8 degrees warmer than normal last month. Rainfall at Belvedere Castle was less than half of the normal 4.23 inches. Don't worry, rainfall upstate was closer to average and the reservoir levels are only slightly lower than they typically are at this time of year. more ›

This October, artist Thom Sokoloski will build 100 white tents on Roosevelt Island, and the public will be able to see the illuminated tents at night as well as explore what's in them. The project is called The Encampment and here is a description the website:

The Encampment is a large-scale public participatory art installation. 100 - 19th century luminous tents will be erected as a work of optical art on Roosevelt's Island Southpoint. From 7pm to 7am each night, New Yorkers will be able to view the luminous symmetries of the tents from both sides of the East River, as well as visit the actual site and experience the installations in each of the tents. It proposes an archaeological dig as its metaphor; the search for artifacts is replaced by the search for a collective memory of Roosevelt Island.

Open House New York opens the doors to many New York spaces that you wouldn't likely ever see. Past tours have included 7 World Trade Center and the Lost City Hall Subway. Each October these tours are free, and throughout the year the series costs money. The Spring tours will include: more ›

The General Theological Seminary takes up an entire block of West Chelsea between 9th and 10th Avenue. The seminary is the oldest Episcopalian seminary in the country-- it was founded in 1817! We've been peering through the bars for years on the way up to the galleries in Chelsea, and now, courtesy of Open House New York and our pal What I See, we finally get to take a peek inside. Check out his outdoor shots, as well as some interior pictures. And if you are interested in beautiful NYC seminaries, you should also check out the cloisters at Union Theological Seminary up in Morningside Heights.

And like that Open House New York is over(ish). Our general impression has been that the rain and icky weather really kept people away this year. But that's just our impression. Anyone have any good stories? Take, or find, any good pictures? That's what comments are for. more ›
