Sefton Park in Liverpool has been reclassified by English Heritage from Grade II* to Grade I in the Register of Historic Parks and Gardens.
Designed by French landscape architect Edouard Andre and Liverpool architect Lewis Hornblower in 1872, the 235-acre park, has been reclassified, partly because of the fact that very little has been changed since it was first opened.
The park underwent a £5m restoration between 2007-2009 followed by a £6m programme to resurface the roads around the park. The council has also introduced pedalos back on to the lake.
Last week the park played host to Liverpool International Music Festival, with more than 100,000 people attending over the week.
As part of the national review, Wavertree Botanic Garden and Park - also in Liverpool - has also been regraded – as Grade II*, up from Grade II listed status.
