NEW YORK — A new multimedia experience at the Empire State Building Observatory provides additional depth about the building’s history.

The latest technology is combined with consumer-friendly navigation on a handheld device that offers an audio and visual companion through four educational areas: the recently enhanced Sustainability exhibit, the “Dare to Dream” exhibit about the historic construction of the building, and the 86th and 102nd floor observatories.

The experience features “fun” and “info” sections, along with videos, image galleries, quizzes and maps showing points of interest nearby. Antenna International, which has created similar tours at 1,200 sites around the world, from the Louvre to Alcatraz, developed the app.

Visitors are given the multimedia experience free of charge with admission to the observatory at the beginning of their tour.
