The Dorset Historic Environment Record (HER) is a record of historic buildings and archaeological finds and features in the county. Records range from isolated finds of coins or fragments of pottery to massive earthwork features covering many hectares; from the earliest prehistoric periods to industrial sites and World War 2 defences. Wrecks and underwater sites are recorded, as are sites with special designations such as scheduled monuments and listed buildings.

The HER is managed for public benefit and in accordance with national standards; it is actively maintained to be as accurate and comprehensive as possible, to support and ensure the better understanding, enjoyment and protection of our environment.
