Anglesey County Council Records

Scope and Content

Minute books of Anglesey County Council and various committees, [20th century]; and miscellaneous records, 1837 - 1986.

Administrative / Biographical History

Formed under the Local Government Act 1888, the County Council took over many administrative duties of the Court of Quarter Sessions, such as responsibility for roads, bridges, county rates, county buildings, the police force, and licensing. In 1889, the administrative and welfare responsibilities were transferred to the first elected county council (56 members). Further responsibilities in secondary education, technical education and agriculture were added. The Council was relocated from Beaumaris to the new shire hall in Llangefni. The County Council, unusually, was also the Water Authority for the island, 1933-1966, and maintained much of its responsibility for health provision after the National Health Service was established. Anglesey was amalgamated with Caernarfon and Meirionnydd to create the new Gwynedd county council in 1974, as part of the restructuring of local government and a response to the growth in decentralised administration following the establishment of the Welsh Office in 1964. The island continued to be a administrative unit, with the status of Borough Council. Cyngor Sir Ynys Môn/Isle of Anglesey County Council was established in April 1996, as part of Local Government re-organisation, and is responsible for providing all local government services in Anglesey; it has accumulated the collection for deposit.
