"March 12th & 13th 2005
"Sixty years ago, the Allied Forces defeated Japan's Imperial army and brought the second world war to a close. Singapore, which was occupied by Japanese troops from 1942 until 1945, will mark the anniversary of its liberation with a series of special events. The first of these will be to unveil a network of British military tunnels at Labrador Park.
"The park was a strategic site for British troops defending the island. In 2001, two hidden tunnels were unearthed, but public access was limited until now. To get there, take a cab to Labrador Villa Road, or a free shuttle bus from the nearby Harbour Front MRT Station. The event runs from 10am to 6pm.
"Labrador Park, Labrador Villa Rd, off Pasir Panjang."

I'd go to this if I were nearby, but I'm not.
