Castillo del Cerro de los Moros is an 18th-century fortress located in Cartagena, built by military engineer Mateo Vodopich during the reign of Charles III. This structure played a significant role in the War of the Spanish Succession, serving as a strategic point for artillery. The castle features a Neoclassical design and was primarily constructed to protect the Naval Hospital and the San José Gates. Its layout includes three bastions and two curtain walls, with the main entrances located at the north and south bastions.

Visitors can admire the castle from a distance, as access to the interior is restricted. The views from the top are noted to be quite impressive, although the area surrounding the castle has been described as less than inviting, with reports of litter and a general sense of neglect. While the structure itself holds historical significance, the experience may be marred by the environment, which some have found uncomfortable. It's advisable to approach the site with caution, as safety concerns have been raised by past visitors.

The castle is located at C. Sta. Lucía, 33, 30202 Cartagena, Murcia, Spain. There are no entrance fees or specific opening hours since access is limited. To get there, you can take a taxi or walk from the city center, but be prepared for a less-than-ideal neighborhood. If you decide to visit, it's best to go during daylight hours and to be mindful of your surroundings.
