An attempt was made to open this unfinished tunnel in order to facilitate the transport of syenite rock for the production of cobblestones for such important Canarian streets as Vegueta, in Las Palmas de Gran Canaria.
It was intended to connect the Barranco de Ajuy with the refuge of Puerto de la Peña, but in the end it could not be built.
The area drilled for its construction was later used as accommodation for the lime workers.
