Roman Bridge over the Belagua River in Isaba, Navarra (Spain)

There was a palace in which a princess who was suffering from stomach and kidney ailments lived . Her slave Cliastela suggested to go to the source of Liscar, famous for its therapeutic powers, but to reach it was necessary to cross the river by boat and a flood had taken her. The devil appeared to Cliastela as a man and promised to build a bridge during the night (22:00 to 6:00 ) in exchange for her soul. The slave accepted the proposal. The devil just finished work at six o'clock . When Cliastela arrived , she told him the devil to look up the clock tower sun , miraculously marked the seven o'clock .
