Lytton Hill, Heritage-listed signal station in Lytton, Australia

Lytton Hill is a heritage-listed signal station on a knoll about 4 metres above sea level at the south head of the Brisbane River in Lytton, roughly 15 km northeast of central Brisbane. Its surviving structures include the 1873 double-gabled timber telegraph office and residence, built for £534, and earthworks of the redoubt recommended by Colonel Peter Scratchley and General William Jervois.

The station began in the 1850s as a customs post and later became the center for telegraph communications and river shipping monitoring. By the late 1800s, it also served as a youth detention facility and military installation protecting the river approaches.

From 1866 the hill relayed semaphore messages from the St Helena Island prison, which had no telegraph link, and in 1873 tenders were called for a telegraph station and residence costing £534. The double-gabled timber building that resulted is the only survivor of four such Queensland post and telegraph offices, the others being Blackall, St George and Cunnamulla.

The hill is easily reached from central Lytton and provides good vantage points across the water and surrounding landscape. Visitors should be prepared for uneven ground and wear comfortable footwear when exploring the structural remains and overlook areas.

The site once held one of Queensland's oldest surviving telegraph offices, designed specifically for that purpose. This structure from the 1870s ranks among the few original buildings remaining from that era of regional telecommunications.
