 A complex of buildings against the wall at the southern end of the plaza , that included Madrasa Fakhriya and the house that the Abu al @-@ Sa 'ud family had occupied since the 16th century , were spared in the 1967 destruction , but demolished in 1969 . The section of the wall dedicated to prayers was thus extended southwards to double its original length , from 28 to 60 metres ( 92 to 197 ft ) , while the 4 metres ( 13 ft ) space facing the wall grew to 40 metres ( 130 ft ) .
