Accuracy and reliability

Overall accuracy

The registration in the register of both listed buildings and ancient monuments is done manually and with a certain delay in relation to the decision of conservation. There may be overlap between ancient monuments and listed buildings, especially in the medieval ruins and -villages and listed buildings on them, which means that there may be a listed building on a protected archaeological sites, for example by a manor house built on a mound i.e. there are two different recovery periods on the same site.
