Original architectural drawings of the Usher Hall which have not been seen in public since 1910 will be displayed for the first time in the concert venue.

Vintage drawings of the Edwardian venue were recently discovered by an architect in Leicester that traced its roots to Stockdale Harrison & Sons, the architectural practice that won the competition to design the hall in Edinburgh

The archive contains over 200 items including early sketches of the venue, water colour impressions, detailed competition drawings, exquisitely coloured drawings of lighting and sculptural designs, blueprints for heating layouts, ironmongery and terrazzo floors.

Richard Lewis, Edinburgh culture convener, said: "The design's backlash against gothic buildings of the time and the venue's unusual curved walls are as stunning today as they were 100 years ago.

"To rediscover these vintage drawings is one thing but to have them in our archives and put on public display is extra special."

David Patterson, collections manager at the City of Edinburgh Council which owns the concert hall, said: "For us, this is true lost treasure.

"They represent a piece of the jigsaw of the capital's history and we are delighted to be able to put them on show for the first time."

A watercolour by Shirley Harrison, the architect's son, will be displayed. It shows the building in 1914 and the venue's first audience arriving in Edwardian dress.

Since then it has welcomed fans of the Rolling Stones, Fleetwood Mac, Pink Floyd, Dina Ross and the Eurovision Song Contest.

The free exhibition is between May 12 and September 1.
