Your support will enable life-changing educational programmes for children and young people from under-represented communities, help open up critical debate on the big issues that shape the urban landscape today by supporting Open City’s year-round programme of free podcasts, films and advocacy, and help us to keep running the Open House Festival, allowing tens of thousands of people access to places and conversations they are normally locked out of.
