This speculative proposal explores the role of a Jewish Cultural Centre in downtown Kingston as both a civic threshold and a contemporary extension of Jamaica’s last remaining synagogue. Responding to Kingston’s layered history as a colonial port city and a refuge for Jewish communities fleeing persecution in Europe, the project reinterprets traditional synagogue forms through a tropical, urban lens. Materiality, texture, and filtered light are used to reconstruct the symbolic presence of the missing pendentive and dome, translating Byzantine spatial ideas into a deconstructed contemporary language. The result is a cultural visitor centre that connects local Jewish heritage to a wider global diaspora while opening the institution to a broader public.
