for the fire, fought at its height by 19 fire crews, to be brought under control, and several days for it to be completely extinguished. 150 people were forced to flee the flames, but there were no deaths. The University of Edinburgh School of Informatics on South Bridge was badly damaged; the school was a pioneer in the study of artificial intelligence in the 1950s and one of the world's most comprehensive archival libraries in this field was destroyed by the fire. Little current research data was lost in the fire due to offsite backups. In 2005 work began on a new building, the Informatics Forum, which was occupied mid-2008. Also destroyed was the Gilded Balloon, a major venue for the Edinburgh Fringe, and offices for both the Gilded Balloon and Underbelly venues housed in an 1823 listed warehouse by Thomas Hamilton. The Gilded Balloon later moved to premises in Teviot Row House. The site was temporarily used as a Fringe venue again when it became the C venues' Urban Garden during the 2007 Edinburgh Festival. The owners and displaced tenants together with Edinburgh City appointed McGregor CS to act as lead to piece together the interests so that the site could be redeveloped. The site was then marketed widely and six developers were shortlisted. The gap site was then acquired by the property developer Whiteburn, who were granted planning permission in January 2009 to build a new mixed-use development using the site and existing adjacent buildings. Construction began in 2012 and was completed in late 2013. The main components of the development are a small Sainsbury's supermarket, a 259-bed Ibis Hotel, shops, restaurants, a nightclub and a vennel. In 2016, protesters (including local homeless people) camped out in Cowgate to prevent the building of luxury hotel by Jansons Property. The protesters argued that the development might damage Edinburgh's UNESCO status, would displace homeless people, would remove a medical facility for the homeless and would block the natural light of the Edinburgh Central Library. MSP Andy Wightman offered his support to the campaign. Buildings The oldest building lies to the west end, but is sandwiched between other larger buildings and easily missed. It stands on the south side of the street, just west of where George IV Bridge crosses over the Cowgate. This is the Magdalen Chapel, a 16th-century almshouse chapel built with monies left by Michael MacQueen in 1537.
