Cuba is the idiosyncratic sister of the Caribbean, and a large part of its idiosyncrasy stems from having watched as the last half-century passed it by. What was once a cultural hotbed moldered under Communism. Still, there is an embattled dignity in Havana’s dilapidated architecture, whether colonial style or Art Deco or even the midcentury classics; nowhere else does the traveler find this peculiar marriage between the contemporary and the antiquated, with its incongruous traces of the space age, of Spanish flair and Soviet flotsam. There is, too, a unique resilience among Cubans themselves, whose talent for improvisation, for making do with what’s at hand, is legendary. The feeling of living in frozen time is one of Cuba’s most frustrating realities and its most powerful allure. To imagine Cuba without it evokes an almost existential question.
