Boca Chita Key Historic District, Historic district on Boca Chita Key, Florida, United States.
Boca Chita Key Historic District is a protected site on a small island within Biscayne National Park in Miami-Dade County, Florida. The grounds hold a lighthouse, a chapel, a pavilion, and several other limestone structures, all built in the late 1930s and forming a cohesive ensemble.
Industrialist Mark C. Honeywell began developing the island as a private retreat in 1937, adding buildings over the following years. After his death, the property eventually passed to federal ownership and became part of Biscayne National Park.
The buildings on Boca Chita Key were built from local limestone in a style that was common among wealthy Florida estates in the 1930s. Walking through the grounds today gives a clear picture of how a private island retreat looked and felt when it was in active use.
The island can only be reached by boat, with departure points at marinas in and around Biscayne National Park. Visitors without their own boat can rent one or join a guided tour that covers the crossing.
The lighthouse on the property was never approved by the US Coast Guard and was never used as a navigation aid. It was built purely as a decorative feature, with no official function at all.
