Thaba Bosiu, The name Thaba Bosiu means the 'Mountain at Night'. It was in July,1824 when Moshoeshoe and his people took occupation of the mountain which his brother Mohale had reconnoitred.
He named the mountain Thaba Bosiu-Mountain at Night because he and his people arrived there in the evening and the essential protective work took him until late at night. Many years later the news to intimidate his enemies was spread that at night time the mountain grew larger than usual. This is where the Basotho nation was built. The fortress has eight springs and seven passes, the main one being Khubelu. Thaba Bosiu was never conquered by his invaders.
The mountain is flat-topped and it is situated in the valley of the Phuthiatsana River. It is about fifteen miles east of the junction of this river with Mohokare or Caledon that divides Lesotho from the Free State. It rises about 350 ft. from the surrounding valley and its summit is surrounded by a belt of perpendicular cliffs some 40 ft. high on the average.
