The community and electoral ward includes some or all of the areas of the St Mellons estate and Trowbridge, as well as part of the Wentlooge Levels between the mainline railway and the coast.[2] It is bounded by the village of Old St Mellons to the north; Marshfield (in Newportprincipal area) to the east; and Splott and Rumney to the west.
History
Trowbridge largely dates from the second half of the 20th century, when housing spread east from Rumney onto the farmland of the area.[3]
Until 1938, the area was part of the civil parish of Rumney, in the historic county of Monmouthshire.
In 2019, plans for a new £150m waste incinerator plant was proposed by Mor Hafren Bio Power, off Newlands Road in Wentloog, Trowbridge. The facility would burn up to 200,000 tonnes of waste each year, while also generating 15 Megawatts of electricity. It would be only 3 miles from the Viridor plant in Splott. A campaign group was set up by Trowbridge residents and anti-incinerator campaigners.[7]
A final decision on whether the Mor Hafren facility can proceed was expected in 2020.
