Jellicoe Water Gardens

Flower garden path in the revamped Water Gardens

In 1957 Sir Geoffrey Jellicoe, one of the greatest 20th century landscape architects, was asked to design a new town centre park, transforming an area of orchards, watercress beds and ironworks. Jellicoe based his design on a serpent, channelling the River Gade to bring visitors closer to water and nature. His ideas were influenced by the experimental artist Paul Klee and the role of the sub-conscious. Opened in 1962, the Gardens are a rare post-war Modernist landscape and one of Jellicoe’s most intact schemes.


Fifty years after their completion, the Water Gardens were showing their age. In 2017, the Gardens reopened following a restoration project to return them to their former glory, funded by a £2.4 million grant from the Heritage Lottery Fund and the Big Lottery Fund, topped up by an investment of more than £1 million from Dacorum Borough Council. The restoration reinstated Jellicoe’s original design and added new features making the Gardens once again an outstanding public space.

The Water Gardens achieved a Civic Trust Award in 1965 and joined English Heritage's Register of Parks and Gardens of Special Historic Interest in 2010 as an important example of 20th century urban design. Following the restoration, the Gardens received the Heritage and Conservation Landscape Institute Award in 2017 for “the preservation and comprehensive restoration of a significant mid-20th century design".

Features of the Water Gardens

Lake with Fountain (eye of serpent) 

Jellicoe built a new straight channel for the River Gade to create the impression of a long stretch of water. At the southern end, it opens out into a lake with wide views and a fountain marking the eye of the serpent. 

Rock and Roll sculpture 

Hemel Hempstead Development Corporation commissioned this sculpture for the Water Gardens from the French sculpture Hubert Yencesse. It was positioned on the lake, as Jellicoe wanted the figures to appear as if they were "dancing on the surface of the water".

Flower garden 

The ornamental flower garden forms a ‘howdah’ on the back of the serpent. (A howdah is a grand seat carried on an animal’s back, such as an elephant or camel). Its layout follows a symmetrical grid over which Jellicoe’s wife Susan planted bright swathes of flowers, shrubs and roses to break up the formal pattern. Susan Jellicoe worked very closely with her husband, designing the planting for his garden projects. The current planting scheme is inspired by Susan’s original plans.

Friends' building 

This new building for volunteers and maintenance operations features a striking geometric pattern similar to 1960s designs. Close by, the curving tail of Jellicoe’s serpent rests on the mound by Combe Street.

Friends' garden 

This new community garden has raised beds for growing flowers, vegetables and sensory plants, cared for by the Friends and volunteers. Heritage fruit trees from the local area demonstrate cordon growing, and there are houses for nesting mason bees.


Two new murals commissioned for the restoration feature images from the history of Hemel Hempstead - from Gadebridge Park’s Roman villa up to the development of the New Town.

Bridges and terrace 

Jellicoe designed delicate arched bridges with white railings that float across the water. Here they form the fastenings to the howdah and link the flower garden to Bank Court. During the restoration new feature benches were added to the terrace to create space for groups of visitors.

Play area

This exciting new facility was specially designed for the Gardens with play features based on Jellicoe’s serpent theme. Surrounded by sensory planting, the play structures dip in and out of the ground snaking up to a high lookout point.

Weir and fish pass 

To bring the serpent to life, Jellicoe added four weirs, each designed to produce a different sound as water cascades down, similar to a Japanese water garden. Fish passes were constructed as part of the restoration to improve the natural environment. The fish pass breaks up the change in water level into a series of low steps or pools, so fish can swim and leap up and pass around the weir.

Kangaroo Joey and Platypus sculptures 

Designed by Australian sculptor John Downie, the New Town of Elizabeth in South Australia presented these sculptures to the people of Hemel Hempstead in 1963, receiving a copy of Rock and Roll in return. Originally sited in Albion Court they were moved to the Water Gardens to make way for the Marlowes Shopping Centre.
