At 512 feet, this is Brooklyn’s tallest office building. The decoration on its base includes such icons of thrift as bees and squirrels, and even a couple of pelicans. The interior, which its landmark citation identifies as a âœcathedral of thrift,â is decorated with twenty-two different kinds of marble on the walls, floors, columns, and trim. The mosaic ceiling is designed around the signs of the zodiac, and another mosaic masterpiece is an aerial view of Brooklyn. The bank, which takes its name from Brooklyn’s Williamsburg section, retained the original spelling after the neighborhood dropped the last letter in 1855, when it joined the City of Brooklyn.
