ONE of the city's oldest and most intricate buildings is set for a major study into its past and future.
The sprawling Riddle's Court on the Royal Mile, which dates to 1590, is currently used very little, but it is hoped the study will find a more permanent use for it, as well as uncover details of its past.
The work is being undertaken by Edinburgh
World Heritage, along with the Cockburn Conservation Trust. It will be the first time a comprehensive investigation has been launched into the Lawnmarket building's past.
Investigators want to get to the bottom of several mysteries surrounding the building, such as why some staircases lead nowhere, and the reasons behind some of the architecture.
Fiona MacDonald, a conservation architect for EWH, said the survey would be useful from historical and economic points of view. She said: "Riddle's Court is a really important historic survival at the heart of the World Heritage site. We know about some of the past residents, but we don't know exactly how the building has changed over time.
"Back in the 1960s, for example, some council workmen uncovered some spectacular painted panels by the Scottish landscape artist James Norie. Who knows what else lies hidden in the building's nooks and crannies?"
It is hoped the long-term future of the complex, which sits around a courtyard, can be secured. The building is used as an occasional Fringe venue and by the Workers Educational Association for some lectures and exams. There is also a youth cafe, but the structure has no overall purpose.
It is understood that a permanent educational resource of some description is the preferred option, although those behind the campaign are open to options for the council-owned building.
The WEA had already carried out provisional research into the building's history, and would be keen to continue to play a part in its future. Secretary Joyce Cannon said: "Our recent historical research project highlighted important connections to Scottish education throughout the centuries.
"We would like to see the building used as a centre for learning which celebrates our heritage and involves people in its interpretation and presentation, particularly focusing on the great Scottish thinkers associated with Riddle's Court."
The building has long-standing historic connections with famous people over the years.
In 1598 it was used to host a banquet attended by James VI and Queen Anne. It was eventually named after George Riddell, a wealthy tradesman who helped renovate parts of it in 1726.
In 1751, the philosopher David Hume moved to the venue, where he is said to have done much of his thinking.
The Cockburn Association's Jane Robertson added: "With the support from EWH, we are able to develop a detailed understanding of the building and its significance. This will be invaluable to us in informing options for an appropriate and sustainable reuse."
It is unclear as yet how much will be spent on the work.
