Event Description

The Harbour Trust presents the Tunnels and Gunners Tour – a journey into the military history of Georges Heights, one of the precincts of Headland Park, Mosman

Featuring gun emplacements, underground tunnels and other military relics dating back to the 1870s, Georges Heights once played a crucial role in the defence of Sydney Harbour.

During our 90-minute, volunteer-run Tunnels and Gunners Tour, an experienced volunteer guide will lead you through a set of demilitarised fortifications surrounded by coastal bushland, including tunnels off limits to the general public.
