A part of Windsor Castle that's been closed to the public for over 150 years just reopened - and it's been completely revamped. Take a peek inside.

Windsor Castle has been in use for over 900 years. It was first established as a royal residence in 1110 by King Henry I.

The Inner Hall is in a part of the castle which dates back to the mid-14th century, when King Edward III had turned Windsor into a palace. Here's what it looks like today, post-renovations:

In the 1820s, King George IV used the Inner Halls as a State Entrance to welcome his guests.

In 1866, Queen Victoria closed the Inner Hall, hoping to build a smaller State Entrance. But her intention never came to fruition, and the existing hall remained idle for 150 years.

The Inner Hall can be seen as visitors take the near-three mile walk, which was created by Charles II in the 1680s. The Royal Collection Trust also announced that a new path will be opened to the hall, allowing the public to see it for the first time since it was closed over a century ago.
