The Wanamaker building is fascinating. Around Christmas time, they'd turn the 3rd floor into a sort of model Dickensian village to walk through. There's a small chapel with original stained glass by Tiffany, and a wood-paneled ballroom of sorts with ornate ceilings and electric lamps by the original Edison company that are still operating. There's a large room in Egyptian-revival architecture used for fashion shows, and a chandelier-lined ornate grand ballroom with glass atrium that can seat 1,000 people. There also used to be a complete model house you could walk through, and a functional monorail to bring kids around the toy department floor.
