Parliament House, Edinburgh
Parliament House in the Old Town in Edinburgh, Scotland, is a complex of several buildings housing the Supreme Courts of Scotland. The original building was home to the Parliament of Scotland from 1639 to 1707. It is located in the Old Town, just off the High Street section of the Royal Mile, beside St Giles' Cathedral. Buildings in the complex are Grade A listed buildings. Archaeology. Between 1998 and 2004, archaeological investigations were undertaken by AOC Archaeology in the Southern Courtyard. The archaeologists discovered evidence of the medieval occupation of Edinburgh as well as evidence of the  post-medieval Meal Market, and 95 burials from St Giles’ graveyard. Parliament Hall. The oldest part of Parliament House is Parliament Hall, which the Town Council of Edinburgh, at its expense, had built as a permanent home for the Parliament of Scotland, and as such is the oldest extant purpose-built parliamentary building in the British Isles. It was designed by James Murray and completed in 1641. The main interior feature is the elaborate oak trussed flat roof supported on carved stone corbels. Often described as a hammerbeam roof, it is a false hammerbeam, necessitated by the flat roof design . The internal ornamentation is provided by downward thrusting radial struts. The roof of the former Tron Kirk further down the High Street is similar in style but, because of the pitch of the roof, is a true hammerbeam. After the Acts of Union 1707, the Parliament of Scotland was adjourned, and the building ceased to be used for its original function. The records of the Scottish Parliament were kept in the Laigh Hall on the ground floor until they were moved to General Register House in 1789. The stained glass south window was installed in 1868. The Hall was used  for the sitting of courts, but in recent times has been subject to restoration work and now remains open as a meeting place for lawyers. Artwork in Parliament Hall. The sculptor, Alexander Mylne (d. 1643), carved the royal arms over the entrance of Parliament House in 1635 and the two figures of Justice and Mercy on the same building in 1737. Within Parliament Hall there are several fireplaces: the right-hand example of the two smaller fireplaces has carved scenes from The Merchant of Venice. Courts. Even while the old Parliament was still in existence, parts of the buildings were  used for legal cases, and afterwards this became the main function of the building. The building is now used to house the College of Justice and other connected functions. In modern times, the building is chiefly used by the Court of Session, which hears civil cases, whilst most of the work of the High Court of Justiciary, which hears criminal cases, takes place in a dedicated building on the other side of the Royal Mile which formerly housed Edinburgh's Sheriff court. Libraries. The Advocates Library was founded in 1682, and is currently located in a William Henry Playfair-designed  building to the west of the south end of Parliament Hall. It remains a heavily used legal resource. As well as collecting legal works, it was also a deposit library, and in 1925 the non-legal books in their collection were given to the new National Library of Scotland, which is located next to the library, on George IV Bridge. To the west of the north end of Parliament Hall is The Signet Library. It is a private library, funded by members of the Society of Writers to Her Majesty's Signet, who are generally practising solicitors. Construction began in  1810 to a design by Robert Reid, and it presents a classical front to Parliament Square. This façade wraps around Parliament House as well, and replaced the existing Scottish baronial façade.
