Here's how Manhattan's skyline has changed in the 25 years since the 9/11 attacks

• This year marks the 25th anniversary of the 9/11 attacks.
• The World Trade Center site has become a memorial to the 2,977 lives lost.
• Photos show how New York City rebuilt Ground Zero.

These photos show how the attacks destroyed the towers that once defined the city’s skyline, and how New York rebuilt Ground Zero.

The Twin Towers dominated the New York City skyline on this June day in 1999.

Just over two years later, that skyline was horrifically altered.

The top photo was taken on August 30, 2001, while the bottom photo was taken 16 days after the attacks.

The first Tribute in Light occurred on March 11, 2002, across from Ground Zero.

In December 2003, a design for the new Freedom Tower was finally unveiled.

It would come to include multiple new buildings, such as the 1,776-foot-tall One World Trade Center and a 9/11 Memorial and Museum.

The Tribute in Light still shines each year on the roof of the Battery Parking Garage. Here it is, five years after the attacks.

In late 2007, the site still looked the same, as construction was hamstrung by lawsuits, budget overruns, design changes, and a recession.

In 2009, the 9/11 memorial waterfalls started to take shape.

One World Trade Center, also known as the “Freedom Tower,” was just starting to rise from the rubble.

In June 2010, the skyscraper was slowly rising.

By July 2011, the memorial waterfalls were tested, and One World Trade Center’s facade was beginning to reflect the sky.

Here’s the Manhattan skyline in August 2011. You can see the unfinished tower beginning to peek over the other skyscrapers.

The memorial waterfalls officially opened in September 2011, and the museum, seen on the right, opened in May 2014.

By November 2014, One World Trade Center was complete, as were 4 World Trade Center (left) and 7 World Trade Center (right). However, 3 World Trade Center still wasn’t finished.

The WTC Transportation Hub, on which the white Oculus was built, was also under construction in late 2014.

The hub officially opened in June 2016, while 3 World Trade Center was still under construction.

The $50 million Liberty Park also opened in June 2016. From there, visitors can get an overhead view of the Ground Zero memorial.

This photo from June 2018 shows 3 World Trade Center, One World Trade Center, 4 World Trade Center, the 9/11 Memorial and Museum, and Liberty Park, all of which were finally complete.

With construction officially complete, the Manhattan skyline is now forever changed.

Now the tallest building in the US, the gleaming One World Trade Center, pictured in August 2025, towers over the Financial District.

The Tribute of Light was tested ahead of the 25th anniversary of 9/11.
