Camera Obscura & World of Illusions is a tourist attraction located in Outlook Tower on the Castlehill section of the Royal Mile close to Edinburgh Castle. The original attraction was founded by entrepreneur Maria Theresa Short in 1835 and was exhibited on Calton Hill.
On 26 April 1843, Maria married Robert Henderson, at Saint Cuthbert's, Edinburgh, [2] and in 1852 bought the Laird of Cockpen's townhouse on Castlehill, now known as Old Town, Edinburgh. With the help of sponsors she added an extra two floors and a viewing platform with a dome housing a camera obscura .
Short's daughter Maria Theresa Short was to return to Edinburgh in 1827. She ran a second – a popular and commercial rather than scientific – observatory elsewhere on Calton Hill. In 1850 this was removed [3] and she moved to Castle Hill, where her enterprise eventually became today's Camera Obscura on the Royal Mile.
