1. Flatiron Building
   Empire State Building

The design of the Empire State Building is pure '30s Art Deco, but the 1950s also influenced this NYC landmark. The tallest building in the world at the time — 1,250 feet — it gained additional height with the addition of a TV antenna in 1950. It was during this period that the building began to generate a profit for its owners for the first time.

   Raleigh County Memorial Airport

Designed in 1958 and completed in 1962, the main terminal building at Dulles International Airport has a sleek style thanks to architect Eero Saarinen, who's also known for creating the St. Louis Gateway Arch. Many thought Dulles would be a flop because it was situated far outside Washington, D.C., but it quickly became a major travel hub, particularly for those flying internationally.

1. Desert Inn
   Circus Circus
2. Mirage
   MGM Grand

The Desert Inn had just 300 rooms when it opened in 1950 as the fifth resort on the stretch of neon we now know as the Vegas Strip.

1. Torre de Madrid
   Joseph Cross Tower
2. Tokyo Tower

1. Metropolitan Life North Building
   Prudential Tower
2. Woolworth Building
   Ford Tower

It's a gorgeous example of Art Deco standing 451 feet tall near Madison Square Park, but the Metropolitan Life North Building (also known as 11 Madison) was actually a product of the '50s. Construction began in 1932, hence the Art Deco styling, but was interrupted because of the Great Depression, so this limestone and marble structure wasn't completed until 1950.

1. Hiroshima Peach Memorial Park
   Pearl Harbor International Memorial
2. Chapel of Nagasaki
   Tomb of Tokyo

During WWII, the Enola Gay dropped the first nuclear bomb onto the city of Hiroshima, Japan.

In 1954, the skeletal structure became the centerpiece of the Hiroshima Peace Memorial Park, a major landmark in the once-ruined city.

Opened in 1959, it's now the most-visited museum in the world other than the Louvre.

1. The Shard
   One Canada Square
2. Westminster Hall

Today, it's home to the London Philharmonic and many major arts events.

1. Rice Stadium
   Ford Field
2. Heinz Field
   Lucas Oil Stadium

1. Basilica San Lorenzo Maggiore
   La Sagrada Familia
2. Seville Cathedral
   Hagia Sophia

Construction of the massive and elaborate La Sagrada Familia, a church in Barcelona, began with grandiose plans in the 1880s. After the death of its designer, fires, war and a serious case of vandalism prevented much progress from being made, construction got underway in earnest in the 1950s. As of 2020, the building is around 70% complete, but you can still tour the nave and other areas.

1. Palacio da Alvorada
   Gran Torre Santiago
2. Plaza de Mayo

1. Memorial Coliseum
   Centennial Stadium
2. Velodrome de Vincennes
   Palazzo dello Sport

Rome's PalaLottomatica, or the Palazzo dello Sport as it was formerly known, is one of many modern landmarks that was initially built to serve as a venue for Olympic events. Opened just in time for the 1960 Rome games, the building is made from prefabbed concrete and topped with a ribbed concrete dome, but what really makes it stand out are the flying buttresses, which are made of modern materials but look just like the supports found in old Gothic churches.

1. Sacre Coeur
   UNESCO Headquarters
2. Centre Pompidou
   Watergate Hotel

Before this Y-shaped structure was completed on the Place de Fontenoy in 1958, the members of the United Nations Educational, Scientific and Cultural Organization met at a Paris hotel.

1. Heathrow Airport
   Dublin Airport
2. Charles de Gaulle Airport
   Leonardo da Vinci Airport

To be fair, the original terminal at Ireland's Dublin Airport was built in the '30s in the International Style of design.

   Stratosphere Tower
2. Hughes Memorial Tower
   Landmark Tower

Built in 1957, Fort Worth's Landmark Tower featured 30 floors spread over 420 feet, making it the tallest building in the city at the time.

1. Ed Koch Queensboro Bridge
   Brooklyn Bridge
2. Mackinac Bridge
   George Washington Bridge

The Queensboro Bridge was built in 1909, connecting Long Island City in Queens to the area around 59th Street in Manhattan.

A cantilever bridge made of steel, the structure famously appears in Woody Allen's 1979 flick, "Manhattan." In March 2011, the bridge was officially renamed the Ed Koch Queensboro Bridge to honor former NYC Mayor Ed Koch.

1. Palazzo Lombardia
   Torre Velasca
2. Teatro alla Scala
   San Siro Stadium

Milan's Torre Velasca has been the subject of controversy ever since it was completed in 1958. Its designers wanted to create a skyscraper that fit in with Milan's historic structures, resulting in a 328-foot modernist tower that is wider at the top than at the bottom, and supported by external struts like those on a medieval lookout tower.

1. Lincoln Tunnel
   Jefferson Tunnel
2. Washington Tunnel
   Kennedy Tunnel

The Lincoln Tunnel has allowed vehicles to travel under the Hudson River between Manhattan and New Jersey since the 1930s.

This decade also saw the construction of the Brooklyn-Battery Tunnel, which connected Battery Park in lower Manhattan to Red Hook in Brooklyn.

1. Mackinac Bridge
   Detroit Bridge
2. Peninsula Bypass
   Motor City Speedway

A deep straight separated Michigan into two peninsulas until the iconic Mackinac Bridge opened on November 1, 1957.

Plenty of people drive across, but the bridge also closes to traffic every Labor Day so pedestrians can travel across by foot.

1. Tropicana
   Mirage
2. Desert Inn
   Sands

The street once called Bond Road was renamed Tropicana Avenue when the massive Tropicana Resort opened on the Las Vegas Strip on April 14, 1957. Designed with a Cuban flair, it survived mob ties in the '70s and has nearly 1,500 rooms and a casino stretching across 50,000 square feet as of 2020.
