Robert Williams town
（重定向自Vila Robert Williams）
Vila Robert Williams (Robert Williams town, now Caála) was the former name of Caála, Cuando Cubango province of Angola, 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.
