Annex B: The Department's Criteria for Scheduling Monuments
B11 The following criteria are used for assessing the importance of a monument and considering whether scheduling is appropriate. The criteria should not be regarded as definitive, but rather as indicators which contribute to a wider judgement based on the individual circumstances of a case. The criteria are not in any order of ranking.
- period - all types of monuments that characterise a category or period should beconsidered for preservation.
- rarity - there are some monument categories which in certain periods are so scarce that all surviving examples which still retain some archaeological potential should be preserved. In general, however, a selection must be made which portrays the typical and commonplace as well as the rare. This process takes account of all aspects of the distribution of a particular class of monument in a Northern Ireland context.
- documentation - the significance of a monument may be enhanced by the supporting evidence of historical records, or contemporary written accounts, or reports of previous investigations.
- group value - the value of a single monument may be greatly enhanced by its association with related contemporary monuments or monuments of different periods. In some cases it is preferable to protect the complete group of monuments, including associated and adjacent land, rather than to protect isolated monuments within the group.
- survival/condition - the survival of a monument’s archaeological potential, both above and below ground, is a particularly important consideration and should be assessed in relation to its present condition and surviving features.
- diversity - some monuments may be selected for scheduling because they possess a combination of high quality features, others because of a single important attribute.
- potential - in some cases, it may not be possible to specify the precise nature of the archaeological evidence, but it may still be possible to document reasons anticipating its existence and importance and so to demonstrate the justification for its scheduling. This is usually confined to sites where there are no distinctive above-ground remains.
- fragility/vulnerability - certain important archaeological remains may be particularly vulnerable to damage or careless treatment and therefore benefit from the statutory protection scheduling confers.
