The Alderman Proctor's Drinking Fountain (grid reference ST566738) is a historic building
on Clifton Down, Bristol, England.
The city of Bristol began supplying municipal drinking water in 1858. To inform the public
about the new water supply, Robert Lang made a proposal though the Bristol Times that public
drinking fountains be constructed. Lang began the "Fountain Fund" in January 1859 with a
donation of one hundred pounds. By 1906, there were more than 40 public drinking fountains
throughout the city.
In 1872, Alderman Thomas Proctor commissioned the firm of George and Henry Godwin to build
the fountain to commemorate the 1861 presentation of <i>Clifton Down</i> to the City of
Bristol by the Society of Merchant Venturers.
**Commemorative plaque**
The three-sided fountain is done in Gothic Revival style. The main portion is of limestone
with pink marble columns and white marble surround. The commemorative plaque is of black
lettering on white marble; the plaque reads, "Erected by Alderman Thomas Proctor, of Bristol
to record the liberal gift of certain rights on Clifton Down made to the citizens by the
Society of Merchant Venturers under the provision of the Clifton and Drudham Downs Acts
of Parliament, 1861, whereby the enjoyment of these Downs is preserved to the citizens of
Bristol for ever." The fountain bears the coat of arms for the city of Bristol, the Society
of Merchant Venturers and that of Alderman Thomas Proctor.
The fountain was originally situated at the head of Bridge Valley Road. It became a sight
impediment to modern auto traffic in the later 20th century. The fountain was moved to the
other side of the road, closer to the Mansion House in 1987. After the move, it underwent
restoration and was re-dedicated on 1 May 1988. It has been designated by English Heritage
as a grade II listed building since 1977.
