Castillitos Artillery battery is located in Cabo Tiñoso, about 20 minutes from Puerto de Mazarrón, in a strategic location that allowed it to control and defend the entire bay of Cartagena and, today, allows us to enjoy breathtaking views over all the natural area of the Sierra de la Muela, Cabo Tiñoso and Roldán and its coast, where the Cabo Tiñoso Marine Reserve is located.


History
This military fortification was projected within the Primo de Rivera Defense Plan and finally built between 1933 and 1936. The buildings of the fortification are built recreating a medieval style, hence it is popularly known as Castillitos since the aesthetics and its crenellated towers remind of a medieval castle. It is built with materials of color and texture that allow it to blend in with its surroundings, in addition to being embedded in the mountain, which makes it quite difficult to recognize from afar, especially from the sea. A clear strategic advantage when talking about a military base.

In order to defend the Cartagena coastline, it was equipped with two 38’1 Vickers guns, model 1926, manufactured in Sheffield (England). Two cannons of enormous dimensions that are still in quite good condition. These cannons could fire a projectile of almost one ton (about 885 kg of steel) up to 35 km away. As an interesting fact, the only time they were fired in military combat was in 1937, just after the beginning of the civil war. While Cartagena’s navy was still under the command of the Republic, they dissuaded the attack of three cruisers of the nationalist side that were intimidated by the power of the defensive armament.


What to do in Castillitos?
The battery of Castillitos can be visited for free. Since it is outdoors, is open to any visitor at any time. You can walk around the fortification enjoying the spectacular views over the sea and the bay of Cartagena, a place surrounded by mountains, cliffs and small coves until your eyes reach the city with its large port. On the sea, in front of Cabo Tiñoso, there are usually large cargo ships waiting their turn to enter the port of Cartagena. In the esplanade are the two large canyons, recently restored and easily accessible to visitors. Taking pictures with these spectacular guns is one of the main attractions. In spite of being obsolete weapons at present, they continue impressing visitors given their size and their particular surrounding. You can also access the interior of the buildings and constructions (be careful, some of them are ruins) and wander through their corridors and rooms, as well as access the watchtowers and observe the views that whoever was in charge of watching the coast had a few years ago. You can have a good time exploring around and discovering interesting places. For example, there are some stairs that go down through a tunnel in the mountain to a guard post in the middle of the cliff.



A lot of hiking trails around
