The area below the castle is not only scenic and an attractive part of Ludlow but is of historical and cultural importance and interest. The Dinham Millennium Green Trust was constituted by Trust Deed on September 11th 1999, and since that date it has been working to restore a working Water Wheel and Mill,  and highlight the importance of sustainable resources. The Wheel is linked to a generator to help offset the building's electricity charges.

The Trust wished the land to remain open to the community, as an area of natural beauty and peace. Firstly the Millennium Green was created, followed by restoration of the old Mill and Water Wheel. Photographic timelines can be viewed all around the Mill and Green, providing a historic backdrop.

Both the Millennium Green and the Mill on the Green can be viewed free of charge, although the cafe is commercial. From educational visits to a family day out, the Green has much to offer and provides a unique view of Ludlow and the River Teme. Its proximity to Ludlow town and Castle creates easy access to parking facilities and other activities which can be enjoyed by all. Dinham is one of very few locations in South Shropshire where access to a river may be freely enjoyed. Dinham was possibly the earliest place of human settlement in the vicinity.
