Despite the special age, the Prince's birthday will take place inconspicuously and at home, The Guardian reports .

The royal family did not visit each other during the pandemic and mainly communicates via video calls and by telephone. The queen and prince have not seen son Prince Charles and the rest of the royal family for several months. The prince will not receive a visit this year and congratulations go through Zoom.

Earlier this month, Buckingham Palace released a photo of the royal couple taken especially on the occasion of the Prince's birthday.

Born in 1921 on the Greek island of Corfu, the prince is the longest-serving husband of a reigning queen in British history. The Queen and Prince have been married for 74 years now.

The Queen also celebrated her 94th birthday in April without a visit. During the height of the coronavirus outbreak, she addressed the British people through a television speech that same month. In the speech, she insisted on the solidarity and determination of her people.
