Two of my great loves — pre-Modern interiors and flea markets — join forces in one fantastic mashup: The Brooklyn Flea’s temporary digs at One Hanson Place.

View looking over the mezzanine rail.

During the colder months (till March 28), The Brooklyn Flea is movin’ on up, from its standard location in an empty asphalt lot to the palatial lobby, mezzanine, and underground vault of the former Williamsburg Savings Bank.

If you’re into this sort of thing, it is quite a special experience. The mosaics on the walls and ceiling are spectacular. The food court can be found behind a 6′-thick metal door in the old vault. Vendors populate the old teller booths. The light streaming through the Gothic windows makes the wares seem to glow with their nostalgia.

No need to spend a dime, even. The space is enough of a treasure.
