Symphony Space, founded by Isaiah Sheffer and Allan Miller, is a multi-disciplinary performing arts organization at 2537 Broadway on the Upper West Side of Manhattan in New York City.

As of 2010, Symphony Space hosts 600 or more events annually, including an annual free music Wall to Wall marathon; Bloomsday on Broadway (celebrating James Joyce's Ulysses); and Selected Shorts, broadcast nationally over Public Radio International.

The intention was to sell fruit, meat, fish, produce, and flowers at inexpensive prices, achieved through large economies of scale.

As was common with Astor's building projects, flamboyance dominated the architecture, including a 290-foot William Mackay sgraffito frieze depicting farmers bringing their goods to market.

The stalls were demolished and the main space was converted into the Crystal Palace, a skating rink, and the smaller basement area became the Sunken Gardens, a restaurant.

Afterwards the interior was rebuilt as a theater again, and in 2002 the space was re-opened as the Leonard Nimoy Thalia, acknowledging the actor's financing.
