Heading west of Batu Maung on the road to Teluk Kumbar, you’ll soon come upon the Penang War Museum, perched on top of the steep Bukit Batu Maung. The former British fort, built in the 1930s, was used as a prison and torture camp by the Japanese during WWII. Today, the crumbling buildings have been restored as a memorial to those dark days. Barracks, ammunition stores, cookhouses, gun emplacements and other structures can be explored in this eerie, atmospheric place, and there are information boards in English all over the site.
