Fort Alice was built in 1864 at Simanggang — now Sri Aman — to hold the Brooke administration's line on the Batang Lupar during the long campaigns against Iban raiding upriver. It is a timber fort, built largely of belian, raised on posts, with a drawbridge and a lookout tower, and it is the most complete of the outstation forts the Brookes scattered across Sarawak.
After decades of decline it was dismantled, documented and rebuilt in a restoration that reopened it as a heritage museum. The displays cover the fort's own history, the Brooke administration on the Batang Lupar and the Iban communities the fort was built to govern. It sits above the same river that produces the benak, the tidal bore that still runs up to Sri Aman.
