Reservations are now open for Open House New York, the annual weekend-long event that opens some of the city's most incredible off-limits space to the public. From October 15-16, get once-in-a-lifetime (or, well, once-in-a-year) access to sites like the catacombs of Greenwood Cemetery, the unopened Phase III of the High Line, and the Edgar Allen Poe Cottage, to name just a few of the dozens of offerings.

As previously rumored, this year there will be a $5 fee for all sites requiring reservations. "The new system will make it easier for participants to take advantage of select programming throughout the weekend, while lessening the administrative burden on those organizations that are gracious enough to open their doors for the public," said an OHNY spokesperson. We'll update later today with some of our top picks for the weekend, but get a head start by signing up for some sites here.
