Mill Green Jubilee Garden

The Mill Green Jubilee Garden can be found adjacent to the Mill Green Museum & Mill. To commemorate the Golden Jubilee of Queen Elizabeth II, the designer created a modern garden influenced by the Tudors.

With an attractive riverside setting where you can enjoy a picnic during fine weather;  two long herb beds provide scents and flavours along with flower beds adding colour and beauty to help you relax. The knot garden is based on a design by Thomas Hill dating from 1577. It is an adaptation of the Duke of Buckingham's heraldic badge.

The Garden is open at the same time as Mill Green Museum
