Saint Anne's Park, Urban park in Clontarf and Raheny, Dublin, Ireland

Saint Anne's Park is a 240-acre public park between Clontarf and Raheny in Dublin, bisected by the small Naniken River, whose diverted water feeds an artificial duck pond. About ten surviving garden follies stand mainly along the river, among them a holy well covering, three classical buildings, two decorative bridges, a rustic cave, a shell house and a yew circle with a pool. The grounds also hold a walled garden, a rose garden, a Chinese garden and the Millennium Arboretum.

The land was part of the Guinness family estate until Dublin Corporation purchased it in 1939 and converted it into public parkland. This transformation preserved the Victorian structures while opening the space to the community.

The park's name comes from the Holy Well of Saint Anne, spelled slightly differently from the estate name. Lord Ardilaun planted evergreen oaks and pines along the main avenue and boundaries, and these trees still line the approach. A plaque unveiled by Dublin City Council in 2023 marks the former home of writer Seosamh Mac Grianna.

The park is accessible during daylight hours with multiple entrances and parking areas throughout the grounds. Visitors should wear comfortable shoes as paths wind through wooded sections and the follies are spread across the expansive terrain.

The grounds hide unexpected structures including a Roman tower and a Pompeian-style temple connected by woodland paths. These eccentric buildings were an expression of Victorian landscape design and still surprise visitors expecting a conventional green space.
