Google Maps
Established in 1936, North Fort is a remnant military complex at North Head Sanctuary in Manly.

Strategically placed at the northern entrance to Sydney Harbour, the fort was part of a defence system that spanned 300km of coastline during the Second World War.

The Defence of Sydney Tour is an opportunity to walk in the footsteps of the men and women who served at North Fort. Accompanied by a knowledgeable guide, you will marvel at heritage gun emplacements, once capable of firing 26.4km, and descend into the 200-metre-long military tunnel complex. Finally, our guide will demystify an underground bunker once shrouded in secrecy: The Plotting Room. As you explore this facility, concealed within bushland, you’ll hear how our specialist volunteers faithfully restored it.
