Mahayana Buddhist Temple

Welcome to Canal Street. Six subway lines run under your feet, and the walk starts here, outside a Buddhist temple, on one of the loudest corners in Manhattan.

Most walking tours ask you to look up, at facades and cornices and rooflines. This one asks the opposite. The subject today is ground: what is underneath it, and who decided what got built on top.

Below these blocks the land is soft, wet and made. Not naturally -- somebody made it that way, in a hurry, two hundred years ago, and the whole neighbourhood has been living with the consequences ever since.

Ten stops, about a kilometre and a half, ninety-five minutes. We begin in a Chinatown that is entirely present tense, working, indifferent to all of this, and from there we go downward. Through a slum that is gone. To a pond that is gone. Past the courthouses built on its fill. And finally to a burial ground older than any of it.

Almost nothing I describe is visible. That is not an accident, and it is the reason for the walk.

Let's begin.

Look up before you go in. The red awning says Mahayana Buddhist Temple, but the bones of the building are pure movie palace: a wide, shallow facade, a recessed entry where a ticket booth used to sit, the kind of proportions built for a marquee and a line of people waiting to get out of the weather. This was the Rosemary Theater, and for most of the twentieth century it did exactly what buildings like it did all over the city -- it showed movies, Cantonese-language pictures and kung fu double bills in its later years, to a neighborhood that came here for two hours of dark and air conditioning. In 1997 a Buddhist congregation bought it outright and did something very simple with it: they kept the shape and changed everything inside.

Step through the doors flanked by the two stone lions and the street noise drops by half. The room is still theater-shaped -- a long rectangle running back from the entrance, sightlines all pointed toward one wall -- except where the screen used to hang there is now a sixteen-foot Buddha, gilded gold, lit from below so the face seems to float above the incense smoke. Count the offerings crowded around the base if you have a minute: fresh fruit, folded paper, small dishes of coins, a rack of printed fortune slips that visitors shake loose from a numbered cylinder and trade for a strip of paper with their luck written on it. None of it is arranged for you. It is arranged for the people who come here on an ordinary Tuesday, which is most of who is in the room.

Nobody designed a cinema-turned-temple as a statement. This is what adaptive reuse looks like when it isn't an architecture-school exercise -- it's a congregation without much capital finding the cheapest large room on the loudest corner of the block and making it sacred by force of use. A movie theater is, structurally, an excellent shell for a shrine: open floor, high ceiling, one wall built to hold everyone's attention. Swap the projector's target for a statue and the building barely notices the difference in program. You'll see this instinct again walking through Chinatown this morning -- storefronts, garment lofts, tenement ground floors, all put to a second and third use because nobody who settled here had the money to build new. The temple is just the boldest version of a citywide habit: whatever's standing, and whatever's cheap, gets reoccupied and remade rather than replaced.

And the corner they chose is almost aggressively wrong for contemplation. You're standing at the exact point where Canal Street funnels traffic into the Manhattan Bridge approach -- buses, delivery trucks, a steady bass line of horns that never really stops, day or night. It is, block for block, one of the least peaceful spots in Lower Manhattan to put a shrine, and that seems to bother nobody inside. The roar is just weather here, the same way it was weather for the moviegoers who used to duck in from this same sidewalk decades ago. Push back out through those doors in a minute and you'll be standing right in the middle of that noise again, on the street whose name is about to tell you something about what used to run underneath it. For now, just notice how completely the sound falls away the moment the door swings shut behind you, and how little that quiet has to do with the size of the room -- a converted screening room, on a bridge ramp, doing exactly what it was built to do the first time around: hold a crowd's attention, and let the city outside disappear for a while.
