Grade II* listed buildings in Somerset

These unitary authorities include areas that were once part of Somerset before the creation of Avon in 1974.

[2] Listing was begun by a provision in the Town and Country Planning Act 1947.

Once listed, strict limitations are imposed on the modifications allowed to a building's structure or fittings.

In England, the authority for listing under the Planning (Listed Buildings and Conservation Areas) Act 1990[3] rests with English Heritage, 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.

Grade II* structures are those considered to be "particularly significant buildings of more than local interest".
