Recently, I spent a day of urban exploration at this decommissioned military fort, Mount Imbiah Battery in Sentosa. This defence post was built in the 1880s and by the First World War, Mount Imbiah Battery was emplaced with a 9.2 inch coast gun. It served as an "examination battery", to screen all merchant vessels before allowing them to enter the Singapore habour.
