The county's architectural, cultural, and environmental heritage is precious and should be preserved. At least what's left of it should be preserved. For the past 25 years, the Dade Heritage Trust has worked to save historic sites (the Cape Florida lighthouse, the Miami Circle), restore historic properties, improve historic neighborhoods, and instill a sense of place and community in Miami's diverse environment. One of the trust's best functions is its annual Dade Heritage Days, a two-month spring celebration of Miami's cultural heritage that gives residents a chance to experience a bit of where their neighbors are coming from. The celebration includes hikes through the county's wild places, evenings of contemplating Haitian art or Miami Beach architecture, Miami River boat rides, and tours of the Miami Circle, Stiltsville, and the Biltmore Hotel. The list goes on.
