The turret from the Brazos Lighthouse was erected near the mouth of the Brazos River in 1895-1896 to aid navigation through the newly constructed jetties into the river. Its light originally came from an oil lamp producing 35,000 candlepower. By 1967 the old lighthouse, now electrified and producing two million candlepower, was determined to be no longer needed. After Dow Chemical Company acquired the property, the lighthouse was dismantled, and this historic turret and its prismatic lens were donated to the Brazoria County Historical Museum.
