The 1882 Act contains a schedule of the initial 68 sites that were covered by the legislation. This schedule exclusively focussed on pre-historic monuments, and covered some of the most famous such sites in the country, alongside some that were felt to be at particular risk at the time.
There were 26 English sites listed in the Schedule, in just 10 counties, including seven sites in Wiltshire. Welsh monuments were represented by one site in each of north, south and west Wales.
The 1882 Schedule included 21 monuments, the majority of which are prehistoric sites. Two are Neolithic, five Bronze Age, eight Iron Age and six from early Christian/Pictish periods, although two of the prehistoric stones also have notable early Christian additions. Those sites now in the care of Historic Scotland are indicated with '(HS)'.
In 1882 the whole of Ireland was under British administration Subsequent legislation for Ireland used the terminology of 'Historic Monuments' which continues in Northern Ireland. Three sites in the Schedule are in what became Northern Ireland, one being in County Armagh and two in County Down. The fifteen sites now in the Republic of Ireland are protected by the National Monuments Service and include two world heritage sites. As with England and Wales, the 1882 selection was overwhelmingly what were thought to be prehistoric sites, although there is now uncertainty on the age of many sites.
