In her 65-year reign, it’s safe to say that Queen Elizabeth II has had the chance to meet some of the world’s most powerful leaders — from South African President Nelson Mandela to U.S. President Dwight D. Eisenhower.

At this year’s Summer Opening of Buckingham Palace (beginning 22 July through 1 October), guests will have the opportunity to view the many gifts the Queen has received from foreign dignitaries over the years.

On display in the State Rooms, the exhibition “Royal Gifts” will feature a selection of more than 250 objects from some 100 countries and territories given as gifts “during State Visits, overseas tours and official engagements, and those presented to mark significant moments in The Queen’s life,” according to the royal collection’s site. In addition, the exhibition will also explore The Queen’s role as Head of State, Head of the Commonwealth and Head of Nation.

Here, just a few of the impressive items visitors will be treated to on their next visit to the palace.
