The Hall of Mirrors is a feature of which famous building?

The Hall of Mirrors, the most famous room in the Palace of Versailles, was built to replace a large terrace designed by the architect Louis Le Vau, which opened onto the garden. The terrace originally stood between the King’s Apartments to the north and the Queen’s to the south but was awkward and above all exposed to bad weather, and it was not long before the decision was made to demolish it.
