Moments from Trump Tower

Completed in 1983 and designed by architect Der Scutt, Trump Tower's six-story atrium on Fifth Avenue exists in its current form partly because of New York City zoning incentives from the 1960s and 70s that granted developers extra building height in exchange for including a privately owned public space, a POPS, accessible to anyone regardless of whether they're a tenant or a customer. The atrium's most striking feature is an eighty-foot waterfall running down pink and rust-colored Breccia Perniche marble, quarried specifically for the building, alongside brass fixtures and mirrored surfaces that were, at the time, considered a maximalist statement of 1980s luxury commercial design.

As a privately owned public space, the atrium is technically required to remain open and accessible to the public during specified hours regardless of the building's other uses, though public access has been a genuine point of scrutiny and dispute at various points since. If you're visiting specifically for the architecture and marble atrium as a piece of 1980s commercial interior design, rather than for any other reason, it's worth going with that narrow, specific focus in mind.
