Take a rare glimpse inside Buckingham Palace's State Rooms where the Queen's thrones are on display

Buckingham Palace is one of London's most iconic buildings.

Although Buckingham Palace's doors remain closed to visitors for most of the year, each summer, its State Rooms — the 19 public rooms where the royal family receive guests and host official and ceremonial events — are open to the public.

The extravagant rooms are full of paintings, fine porcelain, and chandeliers dripping with crystals. They were designed by the architect John Nash, who was commissioned to design Buckingham Palace (formerly Buckingham House) by King George IV.

This year, the rooms opened on July 23 and will close on October 2. Tickets can be purchased on the Royal Collection Trust website.
