In 1986, it was designated a National Historic Landmark, and in 2007, it was ranked number one on the American Institute of Architects' list of America's Favorite Architecture.
Chrysler Building
The Chrysler Building stands as one of the finest examples of Art Deco architecture in the world. Completed in 1930, this 77-story skyscraper briefly held the title of world's tallest building before being surpassed by the Empire State Building just 11 months later. What distinguishes the Chrysler Building is its unmistakable stainless steel crown, adorned with eagle gargoyles and a spire that creates one of the most distinctive silhouettes in the New York City skyline.
Commissioned by automotive magnate Walter Chrysler, the building incorporates numerous automotive motifs, including gargoyles modeled after Chrysler radiator caps and a brick pattern resembling the Chrysler's wheel hubcaps. The lobby is equally impressive, featuring African marble walls, chrome details, and a ceiling mural titled "Transport and Human Endeavor."
Despite its undeniable beauty and historical significance, the Chrysler Building doesn't have a public observation deck, making its interior a hidden gem that relatively few get to experience. Nevertheless, it remains an architectural icon that captures the optimism and exuberance of pre-Depression America.
One World Trade Center
Rising from the site of the original World Trade Center, One World Trade Center (also known as Freedom Tower) stands as a powerful symbol of America's resilience and renewal. Completed in 2014, this 104-story skyscraper reaches a symbolic height of 1,776 feet-a deliberate reference to the year of American independence-making it the tallest building in the Western Hemisphere.
The building's design, by architect David Childs of Skidmore, Owings & Merrill, features a simple, tapering geometric form consisting of eight isosceles triangles. This creates an octagonal floor plan that transitions from a square base to a smaller square at the top, rotated 45 degrees from the base. The tower's exterior is clad in prismatic glass, giving it a dynamic appearance as it reflects changing light conditions throughout the day.
The One World Observatory, located on floors 100-102, offers spectacular views and an educational experience about New York City and the building's construction.

The building's tapered form isn't just aesthetically striking-it's functionally efficient, providing greater stability against wind forces.
The building's 360 CHICAGO observation deck (formerly John Hancock Observatory) on the 94th floor offers panoramic views of the city and Lake Michigan. Its TILT attraction, a moving platform that tilts visitors outward at a 30-degree angle over Michigan Avenue, provides one of the most thrilling architectural experiences in America.
Transamerica Pyramid
One of the most distinctive landmarks of San Francisco, the Transamerica Pyramid stands out with its unique tapered design that has become synonymous with the city's skyline. Completed in 1972, this 48-story building rises 853 feet and was designed by architect William Pereira.
The pyramid shape wasn't merely an aesthetic choice-it was a practical response to the challenge of building a tall structure on a relatively small lot while allowing maximum light to reach the streets below. The building's unusual form also provides excellent seismic stability, an important consideration in earthquake-prone San Francisco.
Two wing-like structures on the building's east and west sides house elevator shafts, stairwells, and smoke towers. The top 212 feet of the building is a hollow spire with a glass pyramid known as the "Crown Jewel" that contains aircraft warning lights and a beacon. While no longer the tallest building in San Francisco (surpassed by Salesforce Tower in 2018), the Transamerica Pyramid remains the city's most iconic skyscraper.
432 Park Avenue
Standing as one of the tallest residential buildings in the Western Hemisphere, 432 Park Avenue in New York City has dramatically altered the city's skyline since its completion in 2015. Rising to 1,396 feet with just 85 floors, this ultra-luxury condominium tower is remarkably slender, with a width-to-height ratio of 1:15, making it one of the most prominent examples of the new generation of "pencil towers."
Designed by Rafael Viñoly, the building features a strikingly simple, geometric form-a perfect square in plan with large, regularly spaced 10-foot-by-10-foot windows creating a consistent grid pattern across the facade. This minimalist design was inspired by a 1905 trash can designed by Josef Hoffmann, proving that architectural inspiration can come from unexpected sources.
The building's extreme slenderness presented significant engineering challenges related to wind forces. To counteract potential swaying, the tower incorporates five two-story mechanical floors that are left open to allow wind to pass through, along with a 870-ton tuned mass damper at the top.
