According to a pool report, the Dolls’ House is 100 years old and was originally built for Queen Mary, consort of King George V. It is the largest and most famous dollhouse in the world.

The first lady and Camilla later visited the Royal Library and interacted with local children from the Eton Porny Church of England primary school.

Melania Trump was dressed in a tan leather jacket and skirt, while the queen opted for a white dress with vertical stripes.

The pair viewed several tiny books made especially for Queen Mary’s Dolls’ House, including Sir Arthur Conan Doyle’s How Watson Learned the Trick and A.A. Milne’s Winnie the Pooh.

Afterward, the first lady met with Kate at Frogmore Gardens, where they were joined by TV personality Dwayne Fields, who serves as chief scout for the Scout Association and hosts nature TV shows.

The princess wore an olive green jacket along with a brown pleated midi skirt and boots.

This marks a historic first for the princess, who joined the first lady without any senior royal family members for their joint appearance.

“This is beautiful,” said Melania Trump as she sat in a chair and examined artwork from the 4- to 6-year-old children who participated in the Scouts division of “Squirrels.”

Kate and Melania Trump gathered with the children to shake a parachute filled with balls, delighting the children, according to a pool report.

The first lady and the princess presented the badges to the children and shook their hands.

“Congratulations!” Melania Trump said.
