Lytton is an outer riverside suburb of Brisbane, Queensland. A pilot station and a village were established at Lytton in 1859. It would be two years before a road was surveyed from Norman Creek. A telegraph line was run from Brisbane to Lytton in 1862. During the years 1876-1908 a local post office was open.
Due to Lytton’s location on the south-east bank of the Brisbane River at its seaward end Fort Lytton was built in 1881 to guard the mouth of the Brisbane River. The fort had a moat and was a pentagonal structure concealed behind an embankment. It was fortified with two six inch disappearing guns.
