Prince William and Kate Middleton visited the church where they got married, which is now a vaccination site

• Prince William and Kate Middleton visited the vaccination site at Westminster Abbey on Tuesday.
• The duke and duchess' visit coincided with the anniversary of the UK's first lockdown.
• The couple tied the knot at the church almost 10 years ago on April 29, 2011.

On Tuesday, Prince William and Kate Middleton visited a place that played a pivotal role in their relationship: Westminster Abbey, the church where they got married.

The church looks a bit different today than it did when they said their vows nearly a decade ago.

According to a press release from Kensington Palace obtained by Insider, the National Health Service (NHS) opened a vaccine center at Westminster Abbey in early March.

The center can "provide up to two thousand life-saving jabs each week to local Westminster residents," as stated in the press release.

During Tuesday's visit, the Duke and Duchess of Cambridge met with both health officials and people receiving their vaccinations, according to the same press release.

Prince William and Kate Middleton's visit was also filled with nostalgic touches since it took place at the site of their wedding.

For instance, the Duke and Duchess of Cambridge walked down the same aisle they did on their wedding day.

Likewise, the duchess wore a white, knee-length coat, nodding to the white dress she wore to marry Prince William.

The Duke and Duchess of Cambridge tied the knot at the famous church on April 29, 2011.

22.8 million people watched from around the world as the royal couple said their vows.

The couple's visit fell on the National Day of Reflection, which marks the anniversary of the UK's first lockdown as a result of the coronavirus, as the same press release stated.

"The Duke and Duchess took part in a private moment of reflection, to remember all those who have lost their lives as a result of the pandemic over the last twelve months" at the end of their visit, the press release said.

At the time of writing, around 28 million UK citizens have had at least one dose of a coronavirus vaccine, according to the BBC. Over 126,000 people have died in the UK as a result of COVID-19.

The press release provided to Insider by representatives for the Duke and Duchess of Cambridge did not address the relationship between the royal family and Prince Harry following his and Meghan Markle's tell-all interview with Oprah Winfrey that aired earlier in March.

Harry has spoken with his family since the interview, but the conversations were "not productive," according to CBS's Gayle King.

On Sunday, the Queen announced she would be appointing a diversity chief because of Harry and Markle's accusations of racism that they made during their interview with Winfrey.
