JAKARTA - Buckingham Palace has 775 royal rooms. Some of them are unexpected rooms. Queen Elizabeth II, 93, has lived in the London-based residence since 1952.

While some of the luxurious interiors and spacious gardens have been caught on camera or seen by special guests, many remain behind closed doors. According to The Royal Family website, the palace has 19 state rooms, 52 royal and guest bedrooms, 188 staff bedrooms, 92 offices and 78 bathrooms.

But did you ever think that the Queen's house also includes a secret cinema, swimming pool - and even a post office?

The BBC's Emily Maitlis says she saw a cinema room - which was actually for staff - being prepared when she arrived to interview Prince Andrew in November.

She wrote in the Times that a worker told her: “This is Buckingham Palace cinema. Everyone who works here comes along. Tonight (will be showing a biopic) Judy if you want to come. '"

Then, what kind of palace is claimed to be complete but without a post office? At Buckingham, all 800 staff members can use the Court Post Office, which is run by Royal Mail.

This post office photo was first taken in 1941, but its current appearance remains a mystery. There is also a doctor's office on site, run by Dr Timothy Evans, according to Hello! Magazine. Again, this is specifically for staff use.

Apart from the post office and doctor, Buckingham Palace also has a private chapel. Created by Queen Victoria and Prince Albert in 1844 in a place designed as a conservatory, it was destroyed in Blitz, a German bomb attack during World War II. This chapel was rebuilt in the southeast part of the palace.

Buckingham also offers a full-sized swimming pool which, again, can be used by staff and the royal family. In fact, Kate Middleton and Prince William reportedly took Prince George there for private swimming lessons when he first started dipping his toes.

And what was hidden in the White Drawing Room was something very mysterious. There is a secret passage disguised as a mirror and cupboard, hidden from view. The door leads directly to the Queen's private apartment.
