The fabulous openhousenewyork Weekend celebrates its tenth anniversary by once again offering people the opportunity to experience the nooks and crannies of many of New York City’s most fascinating architectural constructions. Among this year’s special programs, some of which require advance reservations even though admission is free, are Designers’ Open House, with such interior designers as Thomas Jayne, Ali Tayar, Paul Ochs, Aizaki Allie, Christopher Coleman, and Lea Ciavarra inviting guests into their private homes; the Peace Bike Ride led by Nadette Stasa of Time’s Up!; a treasure hunt for kid explorers at the Park Avenue Armory; “Dance on the Greenway,” with Dance Theatre Etcetera performing site-specific pieces by four emerging choreographers in Erie Basin Park behind the Red Hook IKEA; “Paseo,” consisting of short works by choreographer Joanna Haigood and composer Bobby Sanabria that take place on fire escapes and stoops at Casita Maria in the Bronx; “Spirits Alive,” with actors in period costumes portraying famous people buried in the Maple Grove Cemetery in Kew Gardens; “Wilderness Plan,” in which costumed dancing creatures lead people through the Elevated Acre in the Financial District; and “Frost Court,” a performance installation featuring dancers Jon Kinzel, Silas Riener, Stuart Shugg, Saul Ulerio, Enrico Wey, and Aaron Mattocks. Although some of the special tours are already booked, plenty of others have vacancies or are first come, first served (unless you buy a $150 front-of-line Passport), so you can still check out the Fading Ads of New York City with Frank Jump, the Manhole Covers of Fourteenth St. with Michele Brody, the Museum of Reclaimed Urban Spaces, the Harlem Edge: 135th St. Marine Transfer Station, the Bronx River Right-of-Way, the Kings County Distillery Tour, Historic Richmond Town, the Noguchi Museum, the New York City Photo Safari for shutterbugs, the Lakeside at Prospect Park Construction Tour, the Mount Vernon Hotel Museum & Garden, the Tenriko Mission New York Center, the Alice Austen House Museum, Fort Totten, the Snug Harbor Cultural Center & Botanical Garden, the Grand Lodge of Masons, the New York Marble Cemetery and the New York City Marble Cemetery, the Theodore Roosevelt Birthplace, Scandinavia House, the Morris-Jumel Mansion, Merchant’s House Museum, the Jefferson Market Library, the Little Red Lighthouse, the High Line, the African Burial Grounds, and so many, many more.
