## 5 Conclusions  
The results of this study prove the method is consistent, regardless of the typology and historical period considered. However, they could be refined by increasing the number of towers in the survey--that would enable different curves to be created based on historical period and typology and also slenderness to be studied from the viewpoint of the different geographical territories and areas that comprised the ancient Kingdom of Granada, whose administrative borders remained basically unchanged up until the 19 th century. Such further work would contribute to proposals concerning the characteristics and sections of several watchtowers that have disappeared with the passage of time.

All authors have read and agreed to the published version of the manuscript. This research has been carried out within the framework of the Spanish National R&D Research Plan through the project called \"The watchtowers that defended the Nasrid Kingdom of Granada. Scientific analysis and survey\" (HAR2016-79689-P) funded by the Ministry of Economy and Competitiveness, Government of Spain. The authors would like to thank the city councils of the different municipalities where the watchtowers analyzed are located for their willingness to manage the entrance and the provision of the necessary safety measures.
