The building opened on May 1, 1931, when then President Herbert Hoover officially "flipped the switch" from the White House.
The switch illuminated the building's famous tower lights for the very first time - and is the crown jewel of the city's legendary skyline.

The building's 90th birthday celebrations will last all year long. To kick it all off, the iconic skyscraper will sparkle with a special "90" on the evening of its birthday. And the window display on Fifth Avenue will glitter with all-new jewels by David Yurman.
Guests who purchase select visitation packages will receive a free celebratory 90th-anniversary tote bag while visitors in the entire month of May will be able to get 90-cent Starbucks coffee at the location inside the observatory.
Visitors who head to New York's most famous building will be able to sign up for the building's all-new "90 in 90 Tour" that wraps up 90 years of history in 90 minutes. The tour is true VIP treatment, with guests assigned their own personal building "ambassador" with behind-the-scenes access.
The Empire State Building's Observation Deck temporarily closed to visitors during the pandemic but reopened in July, with new guidance for social distancing and face masks which will remain in place for the 90th celebrations.
