They were also worried that they would be in the direct line of fire if there were any attacks on the fort because the offices along the Singapore River were situated within close proximity to the fort.
The location of the previous lighthouse is now being occupied by The Lighthouse Restaurant, to keep up with the modern style of the Fullerton Hotel.
The General Post Office (GPO) was the anchor tenant, which only moved in a fortnight after the Fullerton Building's official opening.
The fort consisted of an Artillery Barrack, a house for the officers, barracks for soldiers and a 68-pounder gun guarding the entrance to the river which used to stand on the location known as Fullerton square.
