Coral Gables was one of the first planned communities, and its planning was based on the popular early twentieth century City Beautiful Movement. It is infamous for its strict zoning regulations. The city was developed by George Merrick during the Florida land boom of the 1920s. The city's architecture is almost entirely Mediterranean Revival style, mandated in the original plan, including the Coral Gables Congregational Church, donated by Merrick. The domed Catholic Church of the Little Flower was built somewhat later, in a similar Spanish Renaissance style. By 1926, the city covered and had netted $150 million in sales, with over $100 million spent on development.
