Bute Park and the grounds of Cardiff Castle are designated Grade I on the Cadw/ICOMOS Register of Parks and Gardens of Special Historic Interest in Wales. Bute Park Restoration Project From 2007 Cardiff Council undertook a £5.6 million restoration project, which was part-funded by a £3.1 million grant from the Heritage Lottery Fund. The project provided new facilities and restored historic features in the park, including: Summerhouse Kiosk providing refreshments and toilets, built in 2010 to a design that echos William Burges's summerhouse in the park. Animal Wall, designed by William Burges (1827–1881), a stone wall topped by sculpted animal heads, cleaned and conserved in 2010. Blackfriars Friary: Work undertaken to conserve and interpret the medieval Friary remains, using Victorian brickwork walls to mark the building's plan. West Lodge: The restoration and extension of this historic building and gateway provides a visitor information/orientation point, now used as the Pettigrew Tea Rooms. Mill Leat: Reintroduction of water to the old castle moat that runs alongside the original 12th-century mill stream will restore views and enhance the character of the park to the west of Cardiff Castle. Bute Park Arboretum: Improved signage and interpretation will allow increased awareness and understanding of the park's nationally significant tree collection. Education Centre: This new facility is discreetly located within Bute Park Nursery, and playing on the concept of a "secret garden", will be the hub of the park's public education programme. The Council's horticultural staff train here, and it provides additional refreshment and toilet facilities. The park is maintained by a team of Park Rangers and gardeners based on site, who are supported by volunteers.
