 In 1987 the city was selected as a UNESCO World Heritage Site, recognising its international cultural significance.In the 1960s and early 1970s the way in which some parts of Bath were redeveloped, resulting in the loss of some 18th- and 19th-century buildings, led to a popular campaign to change the way the city was developing, which drew strength from the publication of Adam Fergusson's "The Sack of Bath".Since 2000, developments have included the Bath Spa, SouthGate, and the Bath Western Riverside project.
