After the splendour of the beatification of Fernando III in 1671, the Council of the Church of Seville forces the monarchy to restore the front of the Royal Chapel in order to adapt it to the new cult.After several attempts, the task lies in the hands of Francisco de Herrera the Younger by royal imposition, a fact which finally allowed him to get into the court.However the sumptuousness of the design, its modernity and economic scarcity involves the extension of the project for a time, which means the programme cannot be developed in its full scope.
