In 2016 the committee organised a very successful international conference on Capability Brown.

Implementing the European Landscape Convention 2006

Following the great celebrations of the achievement of Capability Brown in last year’s tercentenary CB300 Festival, the Gardens Trust has felt it is important to remind everyone that many of Brown’s actual landscapes continue to be threatened or harmed. They have now published a report, Vulnerability Brown, to highlight this.
