Dade Heritage Trust, founded in 1972, is Miami-Dade County's largest historic preservation organization. Through community based advocacy efforts, partnership with local governments and educational programming, Dade Heritage Trust offers solutions to protect and preserve our community's historic assets. DHT's walking tour and bike tour program explores urban Miami and a new educational program introduces students to historic venues in City of Miami Parks. Year-round exhibits and events introduce Miami residents and tourists to important Miami landmarks and create advocates to save Miami's annual 11 Most Endangered Buildings/Greenspaces Listing.
