This Gardens Trust conference aims to promote the understanding and significance of mid to late C20 designed landscapes - those laid out between the mid 1960s and 1990 - and to review how they might be better recognised and conserved. Covering a wide range of landscapes from urban civic spaces to crematoria, business, institutional, industrial and country parks these designs have often been treated as of secondary importance to both the gardens of the period and to the built architecture of a place; consequently they are poorly represented within national designations. They have often suffered at best neglect and at worst have gone unrecognised, unvalued, poorly managed - and even occasionally been destroyed. Promoting late C20 designs is timely too; 2016 and 2017 mark the 20th anniversaries of the deaths of Geoffrey Jellicoe (8 October 1900 – 17 July 1996) and Dame Sylvia Crowe (15 September 1901 – 30 June 1997).

Key speakers from the heritage world include architectural critic Rowan Moore, landscape architects Oliver Rock (HTA Design), Richard Flenley and Dominic Cole, Historic England’s Director of Listing England, Dr. Roger Bowdler, and Elain Harwood, author and Historic England’s C20 architectural historian and Annabel Downs from the Landscape Institute’s Archive. The sessions will be chaired by Robert Holden, described as ‘the leading European landscape architecture critic of his generation’ and Catherine Croft, Director of the C20 Society.  The conference venue is provided by kind permission of the Garden Museum and forms one of the events celebrating the Museum’s re-opening after its major refurbishment.

The Gardens Trust aims to set up a post-conference project – Compiling the Record - to find out more about these neglected mid to late C20 designed landscapes and, as important, to increase the number offered protection through national designation We would like to find and research 50 sites over the next year or so that might qualify for designation and are calling on everyone interested in these landscapes to explore their cities and regions to identify sites of significance.  We are particularly keen to hear from County Gardens Trust members with detailed local knowledge.  More details on the kind of information needed and how it might best be captured for assessment will be available at the conference.  The Gardens Trust may be able to offer some research and recording training in this rather special period of historic landscape design.

Tickets: £65 Gardens Trust & Garden Museum members; £68 County Gardens Trust members; £75 non-members; £45 registered students. Includes lunch, tea/coffee and private viewing of the Museum’s new galleries. If you wish to pay by cheque please e-mail  We regret no refunds are possible.
