The Memorial to the Heroes of the Marine Engine Room is a Grade II* listed monument located at Pier Head in Liverpool. Built in 1916 and designed by Sir William Goscombe John, it was originally intended to honour the 32 engineers who died in the sinking of the RMS Titanic in 1912. However, due to the heavy loss of life during World War I, its dedication was expanded to commemorate all marine engine room workers who died at sea.

The monument stands about 14.6 metres tall and takes the form of a granite obelisk topped with a gilded flame, symbolising sacrifice and endurance. Around its base are sculpted figures representing engineers, stokers, and coal trimmers, as well as allegorical figures of the four elements—earth, air, fire, and water. These realistic depictions of working-class men were unusual at the time and marked a shift in memorial design toward recognising ordinary workers.

The memorial also carries inscriptions honouring “all heroes of the marine engine room,” and notably makes no direct mention of the Titanic, reflecting its broader dedication. It still bears visible shrapnel damage from World War II, linking it to multiple periods of maritime and wartime sacrifice.
