🏆 Official Guide: The Barnacle Historic State Park — five bayfront acres in Coconut Grove holding the oldest house in Miami-Dade County, the 1891 home of pioneer yacht designer Ralph Munroe.
The Barnacle Historic State Park is a green hush in the middle of Miami — five acres of tropical hardwood hammock and bayfront lawn in the heart of Coconut Grove, hiding the oldest house in Miami-Dade County still standing in its original location. Built in 1891 by Ralph Middleton Munroe, a founder of Coconut Grove and a celebrated designer of shallow-draft sailing yachts, the house takes its name from its distinctive shape — Munroe thought it resembled a barnacle, and its central room is a broad octagon designed to catch the bay breeze.
Munroe was the first commodore of the Biscayne Bay Yacht Club, a title he held for 22 years. He bought 40 acres of bayfront here in 1886; the Florida Park Service acquired the surviving five-acre homesite from his descendants in 1973, preserving the house, boathouse, and one of the last natural shorelines on this stretch of the bay. It’s a day-use historic park with a modest admission.
What Makes This Park Unique
Miami’s Oldest House
The 1891 Barnacle is the oldest house in Miami-Dade County still on its original site — a window into pioneer Coconut Grove before the skyline.
A Yacht Designer’s Home
Ralph Munroe designed some of the era’s finest shallow-draft sailing yachts; his boathouse and a restored sharpie still sit at the water’s edge.
Last Wild Bayfront
Five acres of native hardwood hammock and undeveloped Biscayne Bay shoreline — a rare survivor amid Coconut Grove’s development.
Moonlight Concerts
The bayfront lawn hosts the park’s beloved monthly moonlight concerts and living-history programs.
Things to Do
House tours: Ranger-guided tours of the Barnacle interior reveal Munroe’s ingenious hurricane-smart design, family furnishings, and maritime collection.
Grounds & bay: Stroll the hammock paths to the open lawn and dock, one of the calmest, prettiest views of Biscayne Bay in the city.
Events: Time a visit for a moonlight concert, a sailing program, or a living-history weekend.
