QUB Architecture Formal 2020 In the year of 2020, our annual formal event for the Architecture Society revolved around "Reminiscence", as we were brought back to the 1920s. The theme of the Roaring Twenties can be highlighted with the Art Deco poster, with the St. Anne's Cathedral to be the main backdrop. Dress-codes were introduced in sync with the Jazz Age - gold and liberating.
