Grade I listed buildings in Mendip

In England, the authority for listing under the Planning (Listed Buildings and Conservation Areas) Act 1990[3] rests with Historic England, a non-departmental public body sponsored by the Department for Digital, Culture, Media and Sport; local authorities have a responsibility to regulate and enforce the planning regulations.

The ruined St Michael's church, damaged in an earthquake of 1275,[6] stands on Glastonbury Tor, where the site shows evidence of occupation from Neolithic times and the Dark Ages.

[8] Glastonbury Abbey had a wider influence outside the town: tithe barns were built at Pilton[9] and West Bradley[10] to hold tithes, and a Fish House[11] was built at Meare along with a summer residence for the Abbot (now Manor Farmhouse[12]).

Medieval structures include Farleigh Hungerford Castle, fortified around 1370, and The George Inn at Norton St Philip, used as an army headquarters during the Monmouth Rebellion in 1685, and then as a courtroom to try the rebels in the Bloody Assizes.

The most recent buildings included in the list are churches: the Church of St Peter at Hornblotton, built in 1872–74 by Sir Thomas Graham Jackson to replace a medieval church on the same site,[18] and Downside Abbey at Stratton-on-the-Fosse, more formally known as "The Basilica of St Gregory the Great at Downside", a Roman Catholic Benedictine monastery and the Senior House of the English Benedictine Congregation.
