After World War II, many residents of Puerto Rico moved to Hartford. Starting in the late 1950s, the suburbs ringing Hartford began to grow and flourish and the capital city began a long decline. Insurance giant Connecticut General (now CIGNA) moved to a new, modern campus in the suburb of Bloomfield. Constitution Plaza had been hailed as a model of urban renewal, but it gradually became a concrete office park. Once-flourishing department stores shut down, such as Brown Thomson, Sage-Allen, and G. Fox & Co., as suburban malls grew in popularity, such as Westfarms and Buckland Hills.
