Princess Benedikte arrived in a carriage pulled by white horses, while enthusiastic individuals gathered in the hope of seeing the kingship.

She beamed with joy in a shimmering turquoise dress to which she had added a range of silver jewelry.

Many supporters lined up outside the hotel to wish a happy birthday to Princess Benedikte, who died two years ago.

Princess Benedikte of Denmark, born at a time when Denmark was occupied by Germany, married Prince Richard Zu Sayn-Wittgenstein-Berleburg a year after his proposal in 1967.

The couple settled in Berleburg after the birth of their three children. However, the princess continued to make official commitments on behalf of Denmark.

Benedikte, 75, has unfortunately lost her husband after 49 years of marriage in 2017.

She is now the patron of 31 Danish organizations and five foreign organizations that focus on humanitarian or artistic or sport goals, including the Alzheimer's Association, Green Girl Guides and the World Diabetes Foundation.
