It is listed Grade II* in Historic England's Register of Parks and Gardens.
Each was enclosed by either a wall or hedge, complete with lockable gate to ensure privacy.
Many of them had summer houses built so the family could spend the entire day in the garden, whatever the weather.
In the 1950s the local council (Warwick Municipal Borough) started buying up the plots with a plan to re-develop the hillside and in the 1960s it was designated for social housing.
In 1994, 4 of the summer houses were 'listed' as being of historical interest and in 2000 a Trust was formed to restore the gardens to their Victorian status.
