Norfolk Association of Architects (NAA) is holding the competition, in partnership with Archant's iWitness24, in the lead up to October's Festival of Architecture in Norwich and Norfolk (FANN17). Jerene Irwin, NAA president, said: 'We're very excited to see how this theme is interpreted by Norfolk's photographers and what memory means to them.'

There are two categories, one open to all and one for under 16s. Finalists' photos will be displayed in an exhibition at The Forum in October, with visitors voting for the winners. Amateur photographers can submit up to four images, each up to 1MB in size, via #FANN17 on Twitter, by emailing photo@fann17.org.uk, or via http://norfolk.iwitness24.co.uk (be sure to include FANN17 in your submission). The deadline is September 25. Visit www.fann17.org.uk.
