A newly refurbished Derby Park is be closed in the evenings despite being fitted with new CCTV cameras.
Derby's Arboretum Park will be closed after dark
The historic section of the Arboretum park will be shut after 1800 in the winter and 2000 during summer.
Derby City Council consulted residents and said more than half backed the move and the early closing would keep the park in "top condition".
The security measures come as vandals attacked benches and walls in Matlock's Hall Leys Park, also in Derbyshire.
Several were damaged and graffiti daubed across brand new seats ahead of the unveiling of a multi-million pound revamp..
Police say they are stepping up patrols to make sure it does not happen again.
