For the first time in decades, Semaphore Cottage is open to the public on a regular basis.
Recognised as the oldest surviving building in Battery Point, Semaphore Cottage was originally built as the guardhouse for the Mulgrave Battery, Hobart’s first defensive fortification. Over time, it evolved into the central headquarters for the semaphore telegraph system, which extended from Hobart to Port Arthur. This system, one of the most advanced of its time, could transmit messages across a 54-kilometre chain of stations within minutes.
The cottage’s historical significance was acknowledged in the 1930s when the Shiplovers’ Society of Tasmania led a successful campaign to save it from demolition. Today, the cottage is cared for by Maritime Museum Tasmania.
Step inside and explore its remarkable story and its role in Hobart’s maritime past. Come and discover a hidden part of Hobart’s maritime heritage.
With thanks to the Hobart City Council for their generous support in making these public openings possible.
