Japanese wartime tunnels, former Marine Police HQ [????- ]
These are described on the government website describing local monuments:
During the Japanese Occupation Period [when the compound was used as a base for the Japanese Navy], extensive underground tunnels were constructed beneath the lawn but after World War II, in view of public safety, these tunnels were blocked and the lawn was re-turfed.
The tunnels were destroyed during the recent development works to turn the compound into a hotel & shopping mall.
If you have any memories of those tunnels, we'd love to hear from you.
