The Grade I listed buildings in Somerset, England, demonstrate the history and diversity of its architecture. The ceremonial county of Somerset consists of a non-metropolitan county, administered by Somerset County Council, which is divided into five districts, and two unitary authorities. The districts of Somerset are West Somerset, South Somerset, Taunton Deane, Mendip and Sedgemoor. The two administratively independent unitary authorities, which were established on 1 April 1996 following the breakup of the county of Avon, are North Somerset and Bath and North East Somerset. These unitary authorities include areas that were once part of Somerset before the creation of Avon in 1974.^[1]

In the United Kingdom, the term listed building refers to a building or other structure officially designated as being of special architectural, historical, or cultural significance, Grade I structures are those considered to be "buildings of exceptional interest".^[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.

Each of the districts include Norman- or medieval-era churches, many of which are included in the Somerset towers, a collection of distinctive, mostly spireless Gothic architecture church towers. The prolific construction of the towers—some started before 1360—was typically accomplished by a master mason and a small team of itinerant masons, supplemented by local parish labourers, according to Poyntz Wright.^[4] But other authors reject this model, suggesting instead that leading architects designed the parish church towers based on early examples of Perpendicular design and ornamentation developed for cathedrals—their most important commissions. Contract builders carried out the plans, adding a distinctive mix of innovative details and decorations as new designs emerged over the years.^[5] These are included in the list of towers in Somerset.

Apart from the churches, each area has its own characteristics. Most of Bath's Grade I listed buildings are made from the local golden-coloured Bath Stone, and date from the 18th and 19th centuries. Their dominant architectural style is Georgian.^[6] In the Mendip district, the greatest concentrations of these cluster around the cathedral and abbey in Wells and in Glastonbury. North Somerset features bridges and piers along with a selection of Manor houses. The Sedgemoor district has many buildings related to trade and commerce centred on Bridgwater; while in South Somerset abbeys, priories and farmhouses predominate. Taunton Deane includes the defensive Taunton Castle, similarly Dunster Castle and related buildings in Dunster feature in West Somerset.
