Alongside St Giles, off the Royal Mile, this is home to Scotland's Supreme Courts and one of the oldest venues in the city.
Behind the façade of Parliament House is a collection of buildings ranging over seven floors and containing more than 700 rooms.
The oldest building, Parliament Hall, is nearly 400 years old.
A public exhibition held in the Summer charts the history, traditions and ceremonies of the home of Scotland's Supreme Courts. The display, entitled 'Parliament House, The Hidden Gem', was introduced to celebrate completion of a £58 million redevelopment of Parliament House.
Not to be confused with the Scottish Parliament building at Holyrood.
