Tatton Park Gardens consist of formal and informal gardens in Tatton Park to the south of Tatton Hall, Cheshire, England (grid reference SJ744814). Included in the gardens are an Italian garden, a walled garden, a rose garden and the Japanese garden. The buildings in the garden are the Conservatory, the Fernery and the Showhouse. The gardens are owned by the National Trust and administered by Cheshire East Council. They are on the National Register of Historic Parks and Gardens and have been designated at Grade II*. The gardens are open to the public at advertised times.
The first formal gardens were created around the early 18th-century house and consisted of a walled garden to the south of the house, a formal semicircular pond to its north and formal lines of trees to the east and west. Later Samuel Wyatt set out an avenue of beeches to the south, which is now the Broad Walk. An arboretum was created during the 18th century and additions have been made to it since. The earliest reference to the arboretum is in 1795 when between five and ten species were present. The first formal garden to be created for the present house was Charlotte's Garden, designed by Lewis William Wyatt in 1814. Lewis also designed the sandstone Conservatory which was originally joined to the house by a glass passageway. This was also known as the Orangery because for a time it was used for growing oranges. In the 1830s a copy of the Choragic Monument of Lysicrates in Athens was placed at the end of the Broad Walk. Gardens were established along the sides of the Broad Walk, including the Leech Pool and the area containing the Golden Brook.
