In March 2017 Weston-super-Mare was chosen as one of the 10 successful bids for the first phase of the creation of Heritage Action Zones (HAZ) a scheme where Historic England works with local partners in places with significant historic environment to use that heritage to help build economic growth and other opportunities in the locality.
