A new park in the area, with a lake, was proposed in 1886, on land owned by
Lord Tredegar. The land was covered with
clay pits and also had a
watermill which would need removing. The land for Roath Park was donated to the city in 1887, primarily by
John Crichton-Stuart, 3rd Marquess of Bute. The design was partly the work of Bute's head gardener,
Andrew Pettigrew, but mainly of his son,
William Wallace, in conjunction with the corporation's chief engineer, William Harpur. The first section of the park was officially opened to the public in 1894 and it continued to be opened in sections over the following two decades. Work initially focused on creating the lake from an area of marshland. In 1915 a
lighthouse was constructed in the lake containing a scale model of the
Terra Nova ship to commemorate
Captain Scott's ill-fated voyage to the
Antarctic from Cardiff in 1910. The park's atmosphere today still retains a
Victorian and
Edwardian character; the park itself is locally listed, and the surrounding streets are designated across three Conservation Areas to ensure this quality will be conserved. The park itself is
Grade I listed on the
Cadw/ICOMOS Register of Parks and Gardens of Special Historic Interest in Wales. Waterloo Gardens, Roath Mill Gardens and Roath Brook Gardens have a separate listing at Grade II. In 2003, the park was used for filming for an episode of the TV series of
The Story of Tracy Beaker. In 2019 the BBC reported that the lake had been polluted for several years by unauthorised sewage discharges. In 2024, the path along the southern edge of the park was widened to accommodate a cycle path. ==Nature==
