Question: What is the oldest structure in Miami?
Answer: Cape Florida Lighthouse in Key Biscayne
The lighthouse is as historically fascinating as it is beautiful. It’s the oldest standing structure in all of Miami-Dade County. Though first built in 1825, it was reconstructed in 1846 after suffering extensive damage during the Second Seminole War. After being decommissioned and serving a stint as the headquarters of the Biscayne Bay Yacht Club, it was later restored and a small museum was created that’s stuffed with information about the local history.
