This paper discusses Cristobal de Rojas in Cadiz after the assault by English and Dutch fleet in 1596. After the discussion of over one year, the court approved his project on the fortress of Santa Catalina. According to his own words, his project was made to replace with the project of a castle by Tiburzio Spannocchi. However, by analyzing how the court made the decision, this paper demonstrates that in the court the project of Rojas was not regarded as the alternative for Spannocchi's project because the castle was designed to defend the city not only from the enemy from outside but also from the foreign citizen in Cadiz. However, Rojas's fortress did not have this double function. Therefore, unlike his own words, Rojas's project could not be alternative for Spannocchi's in terms of function as well as size. This paper discusses his activity of estimating the construction cost as professional aspect of a military engineer and also shows similarity between Cadiz and the city Rojas included in his own treatise
