The walls of Cartagena are considered Cultural Heritage of Humanity and are a symbol of the history of the city. 

This project, which lasted almost two centuries and ended in 1796, is currently being maintained by the Cartagena de Indias Workshop School (ETCar), appointed by the Ministry of Culture, and they began the execution of the second stage of cleaning of these national Assets of Cultural Interest (BIC).

This activity contemplated in the Annual Plan of the Fortifications covers the stretch of wall between the bastion of San Ignacio, in front of the pier La Bodeguita, passing by the bastion of the Contaduría, where the Mayor's Office of Cartagena is located, up to the mouth of the bridge and the wall that borders the popular rubber stick.

"Due to its porous and absorbent composition, impurities from acid rains, pollution, smog and other atmospheric agents adhere to the stones that make up the bastions and wall curtains, allowing the development of mosses and lichens, which once their life cycle is completed, end up generating what we know as biofilm," explained Mario Zapateiro, director of the work.

During 2019 Etcar removed biofilm on 4,498 m2 of the surface of the walls, bastions and the Castle of San Felipe, and in 2020 there were 4,151 m2 in these same places.

Cartagena's walls are one of the most important tourist attractions within the city, as thousands of visitors walk along them every day, which is why it is so important for the city to keep them in good condition. 

The walled cordon is a 15-minute drive from the Rafael Núñez International Airport, for those coming from national or international destinations. Those entering the city from the Cartagena Transportation Terminal are 45 minutes away from this heritage site.
