Source-derived summary

Carysfort Reef Light is located on Carysfort Reef east of Key Largo, Florida. The lighthouse has an iron-pile foundation with a platform, and a skeletal, octagonal, pyramidal tower, which is painted red. The light was 100 feet (30 m) above the water. It was the oldest functioning lighthouse of its type in the United States until it was decommissioned in 2015, having been completed in 1852. The light last installed was a xenon flashtube beacon. It was added to the National Register of Historic Places in 1984.

The reef

Carysfort Reef is named for HMS Carysfort (1766), a 28-gun Royal Navy post ship that ran aground on the reef in 1770. The reef is one of the most dangerous on the Florida Reef tract which parallels the Florida Keys. Of the 324 ships that were known to have wrecked on the Florida Reef from 1833 through 1841 (during the period the lightship Florida was stationed at the reef), 63 did so on Carysfort Reef. The United States Lighthouse Board reported that "Carysfort Reef picks up twenty percent of all the wrecks between Cape Florida and the Tortugas, a space of 200 miles (320 km)."

Lightships

A survey of the Florida Keys in 1823 to locate sites for potential lighthouses and other aids to navigation produced a recommendation that a "floating light", or lightship, be placed on Carysfort Reef.

Editorial analysis

Why this record matters

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 3, 2026.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
