Geocaching has led me to explore many lost, abandoned and hidden places, both in and beyond Singapore. Crawling through tunnels, exploring hidden bunkers and climbing up ladders... these are some of the otherwise unthinkable things I have done in the name of finding that next amazing cache.
Singapore has its own selection of caches in abandoned buildings. Forgotten palaces, the old WWII batteries and bunkers, lost railway lines, and even the occasional dark and scary tunnel. I hope that this challenge will motivate you to go try out some of these caches and live a geocaching life that is on the wilder side. So, are you game? If you are, here is what you need to do:
Find at least 13 caches which have the "Abandoned Building" attribute.
The attribute icon looks like this: 
Caches of all types with the attribute will be counted. The caches can be both in and out of Singapore, and both active and inactive caches will be considered. As with all challenge caches, if you do not meet the criteria, your log will be deleted. But, I am sure all of you cachers have integrity, and I will not have to do anything as nasty as that. You can check if you have fulfilled the challenge here:
The cache is located at the Imbiah Battery, located on one of the three highest points of Sentosa Island (formerly known as Pulau Blakang Mati). The battery is one of the 4 coastal defence structures that protected the Western entrance to Keppel Harbour in the years before WWII. The other defences in the area (Siloso, Labrador and Batu Berlayer) already have caches placed near or on them, so this cache "completes" the set. Imbiah Battery had 3 9.2-inch guns, along with all the usual accoutrements of a coastal battery: ammo reccesses, an ammo hoist, a magazine, shelters and position finding cells. A good place for some exploration and a bit of hiking. I hope you will have fun exploring the area!
