The majority of Signal Hill, including Cabot Tower, is designated a National Historic Site.

Due to its strategic placement overlooking the Narrows, the only entrance to the harbour, fortifications date back to the mid 17th century.

The practical uses of the building were flag mast signalling, and a Marconi wireless station which has since been moved to St. John's International Airport.

On 12 December 1901, the first transatlantic wireless transmission was received by Guglielmo Marconi in the abandoned fever and diphtheria hospital, which has since been destroyed by fire.

Wearing full military uniforms from each period, the soldiers give a display by each section and portray the drills and battle tactics of the time.

[8] The Burma Road trail, built by American servicemen who manned coastal batteries on Signal Hill during the Second World War, runs from George's Pond, Signal Hill Road to Cuckold's Cove, close to Quidi Vidi.

Stoneworks and panels explain the local geological formations, botanical species, and traditional uses of stone.
