 Until the 1970s, the pogrom of 1190 was often underplayed by official histories of the castle; early official guides to the castle made no reference to it.In 1978, however, the first memorial tablet to the victims was laid at the base of Clifford's Tower, and in 1990 the 800th anniversary of the killings was commemorated at the tower.Recently, commercial interests have sought to introduce retail development to the area surrounding it.
