These were generally called Fora Venalia in Roman times, and this term added to a proper name denotes a market or borough town (e.g. Blandford Forum).

The hundred of Wells Forum encompassed the ancient Forest of Mendip, which occupied the northern part; and extended to the south into the lowlands of East Sedgemoor.

[4] Its neighbouring hundreds were Chewton to the north; Whitstone to the east; Glaston Twelve-hides to the south; and Bempstone and Winterstoke to the west.

[4] The hundred covered around 30,000 acres (12,000 ha) and included the parishes of Binegar, Cranmore West, Dinder, Evercreech, Litton, Priddy, Westbury and Wookey.

[5] Although the Hundred was never formally abolished, its functions ended with the establishment of county courts in 1867[6] and the introduction of districts by the Local Government Act 1894.
