Where are the Submarine Tunnels?
The Submarine Tunnels are located near Rabaul. Some estimate that there are 55O to 800 kms of tunnels.
"Some are concrete lined, some were supported with palm trunks, others are hewn from the pumice and coral. Some today have fallen in because of the gurias, many are filled with thousands of bats and bat dung; some have ancient ammunition that no one wants to handle; one by the main road near Vulcan has five supply barges stored in line; most have been swept clean of what they held; occasional ones are found as they were left at war's end."
