It looks like it’ll be a mighty fine weekend, perfect for taking a walk around one of the city’s most changed neighborhoods, Tribeca. Once a downtown hotspot for manufacturing warehouses and other trades, today many of the fine buildings built for those industrial purposes now contain condos or other residences. (What else is new, eh?) There are a few modern specimens scattered about, too, for some dabbling into 20th- and 21st-century styles. From the old-school firehouse that featured in Ghostbusters to a modern, flame-shaped synagogue built in 1967, here’s a roundup of some notable, historic, and just plain fun architecture you won’t want to miss.
