Crowds gathered to celebrate the centenary of Murray Park as part of efforts to preserve it for another 100 years.
Children took part in football and basketball tournaments, and enjoyed face-painting at the park in Kneller Road, Whitton, during Saturday (September 20) afternoon.
They also designed plates inspired by the park's history, which were judged by 96-year-old actress Maggie Rennie (nee McGrath), of Brinsworth House retirement home for actors in Twickenham.
The day ended with a pedal-powered dusk screening of comedy The Addams Family, with viewers taking to bicycles provided by Action Bikes in Whitton High Street.
The event was organised by users of the park in conjunction with the charity South West London Environment Network (SWLEN), using a £3,600 grant from Richmond Council.
Colin Cooper, chief executive of SWLEN, said about 700 people attended over the course of the day, including 80 visitors who expressed an interest in joining a new friends group to help look after the park.
He said he hoped to get the group set up before Christmas so they could begin lobbying for the park and planning a similar event next year.
"Friends groups are the best way of protecting parks in the long term because councils don't protect parks, local people do," he added.
"Murray Park is one of the largest parks in Richmond without a friends group so it's important to get one up and running."
