This study, which focuses on the city of Valencia, specifically in its protected historic centre, the Ciutat Vella (old city), has analysed the influence and traces of the different urban development theories which emerged in the late 20th century; their planning and how such theories, along with land and heritage legislation and social stakeholders, have contributed to the changes in the city.
