In the 6th International Congress of Architects (1904, Madrid) was adopted a six-point recommendation concerning preservation of architectural monuments, which was made from two proposals written by architects, Louis Cloquet and Luis Maria Cabello. 'Preservation of monuments' was one of the most important themes that had been discussed since the 4th International Congress of Architects, so these discussions would have also some influences in forming the conservation theory in the recommendation. In fact, Cloquet's proposal reflects different opinions stated at preceding Congress, in particular, that of Petrus Josephus Hubertus Cuypers.
