Aerial Survey Report: Aerial Investigation and Mapping at Royal Fort Gardens, Bristol

A UAV photogrammetric survey in August 2025 recorded parch marks on the southern lawn of Royal Fort Gardens, University of Bristol. The imagery produced detailed orthophotographs and elevation models, identifying twenty-nine features, twenty-one of probable archaeological origin. Several align with the projected line of the seventeenth-century Royal Fort wall, confirming earlier reconstructions, while others reflect later Repton-era landscaping and modern services. The results refine understanding of the fort’s extent and demonstrate the value of UAV photogrammetry as an efficient, non-invasive method for investigating and monitoring complex historic landscapes.
