It stands 230 metres (755 ft) tall including its 28-metre (92 ft) mast (202 metres (663 ft) excluding the mast) making it the tallest building in the City of London financial district and the third tallest in Greater London and the United Kingdom, after the Shard in Southwark and One Canada Square at Canary Wharf. The Heron Tower is located on Bishopsgate and is bordered by Camomile Street, Outwich Street and Houndsditch.
Construction of the building started in 2007 and was completed in 2011. It is owned by "Heron International" and in May 2014 a 15-year naming deal renamed the building as the Salesforce Tower, after the tenant Salesforce.com, which occupies six floors and 18% of the building's total office space. City of London Council members overruled the name change and voted in favour of calling the property 110 Bishopsgate. The tower initially struggled to attract tenants in the depths of the Great Recession, but is now 90% leased or under offer.
The tower was designed to form the centrepiece of a larger Heron Plaza development, incorporating new public spaces and a network of squares and gardens. In July 2009, Heron International confirmed that it had signed heads of terms with Four Seasons Hotels and Resorts to develop a mixed-use project adjacent to Heron Tower. In January 2011, Heron announced that planning permission for the development had been secured. In August 2014, Heron sold the site, with planning permission, to UOL Group, who said it would push ahead with the scheme and operate the hotel under its 'Pan Pacific' brand.
