History
Vila Robert Williams was the former name of Caála, in the then Portuguese Angola (before 1975). The town of Robert Williams was just west of Nova Lisboa (now Huambo) and was remarkable for huge outcroppings of boulders that jutted from the fields just outside the town. In those outcroppings researchers could find pottery shards, primitive metal smelting pits, and other archeological detritus.
