Photos at Brooklyn Bridge Park, Plays at Morris-Jumel When the Miser was younger and needed the money, guarding one of the world's greatest art collections in a majestic Fifth Avenue fortress didn't seem like such a horrible prospect, even if the uniform sure wasn't anyone's idea of sexy. Summer weekends were tough, though. Long stretches were spent gazing out of available windows, neglecting priceless artifacts. Our holdings of works from Africa, Oceania and the Americas, for example, could have been greatly reduced thanks to the more prosaic distractions of Central Park in summer. Think about that next time you read of some daring art heist somewhere. Sam Barzilay Visitors at last year's Photoville, which is housed in shipping containers. Art shows are more typically indoors than out, but in the summer, unless you're seeking air-conditioning or refuge from the rain, a museum or gallery is unlikely to top your list of places to while away an afternoon. Photoville, a new and ambitious free exhibition opening this weekend in Brooklyn Bridge Park, represents a perfect compromise for New Yorkers torn between basking in warm fresh air and imbibing cutting-edge culture. Using a few dozen shipping containers as exhibition spaces, the event will show the work of photographers both famous and emerging, as well as that of contest-winners whose pieces will be featured on "The Fence," a thousand-foot mesh banner running through the park. On top of this feast of still photography there will be lectures and panel discussions; artist-led classes; a food and beer "garden" featuring several of the city's most popular food trucks and beer from Brooklyn Brewery; and what must be recognized as a touch of subtle genius: a "photo dog run." When was the last time you were able to take a four-legged friend gallery hopping? The event, which continues through July 1, will occupy the rambling expanse of former docks recently reclaimed for transformation into an idiosyncratic yet inviting green space beneath the Brooklyn Heights promenade and the Brooklyn-Queens Expressway, set against the backdrop of the East River and Lower Manhattan. Friday from 4 to 10 p.m., Saturday from 11 a.m. to 10 p.m., Sunday from 11 a.m. to 7 p.m.; Pier 3 Uplands at Brooklyn Bridge Park, Brooklyn Heights; photovillenyc.org. There are so-called drawing-room plays, and then there are plays staged in a drawing room. This weekend the People's Theater Project is presenting the Uptown Festival of New Plays at the Morris-Jumel Mansion in Washington Heights, featuring new works in progress. Admission is pay what you can, and the Sunday afternoon performance will be followed by a garden party. Perched regally at the foot of Highbridge Park in the southeast corner of Washington Heights, the house alone is worth seeing. Saturday is family day from 11 a.m. to 4 p.m., and free admission includes colonial-era games and crafts, and guided tours of the house and gardens.
