“There was a time not so long ago when people would hike to the Gatehouse pumping station at 135th Street and Convent Avenue in Harlem just to stand at a railing inside and watch the water rush by below. The water is still there, coursing its way underground to points south in Manhattan, but the building above now offers a different kind of spectacle. The architect Rolf Ohlhausen set out to evoke the public-works legacy of this rugged 1890 building in transforming it into a brand-new 192-seat performance space for Harlem Stage/Aaron Davis Hall. … (The) $21 million theater (is) the first new performance space to open in Harlem in a generation.”
