This thesis focuses on public sexual possibilities for queer men. Gay men have always had to rely on a hidden vernacular in order to navigate the outside world. In the 1900s, Polari was a secretive slang that served to determine one’s sexuality as well as allow gay men to speak without exposure. Cruising, the practice of seeking sex in public spaces, has long since been written into urban history. This thesis translates communication among gay men during cruising into a new form of architectural polari. Through small-scale interventions, Cruising the Island shows the implications of using churches, grocery stores, and other non-sexual locales as subversive spaces to accommodate cruising.
