The Dell is a little park situated between Warwick Place and Beauchamp Hill in Milverton, Leamington Spa. It is delightfully secluded like a sunken garden with a grassy area surrounded by trees, flowers and shrubs. It is maintained by Warwick District Council with the active support of Friends of the Dell and the GALS.
