The Calar Alto Hispano-German Astronomical Observatory is situated in the Sierra de Los Filabres, north of the province of Almería, and is operated jointly by the Max-Planck Institute of Astronomy in Heidelberg (Germany) , and the Institute of Astrophysics of Andalusia (CSIC) in Granada.

The historical antecedents of the castle date back to the Muslim era, due to its great strategic value as a place of surveillance at the crossroads that linked Almería with the Sierra de las Filabres. During the Re-conquest, the Christian troops occupied it and demolished it to prevent uprisings.

The bridge is an important engineering work of the late nineteenth and early twentieth centuries. Its construction began in 1880, but due to problems that appeared in the land, it was delayed for about 28 years.

The church was built from 1640 onwards, opposite the site occupied by the previous Iglesia de Santa María, which was destroyed during the Moorish Rebellion. It was renovated in 1771 according to the project of the architect Francisco Ruiz Garrido de Vera.

The date of the Chapel is unknown, however, it appears in Gérgal’s plan in Pascual Madoz’s “Geographical-Statistical-Historical Dictionary” made between 1845-1850. On its main facade reads the inscription: “Ermita San Sebastián (1734)”.

The Tourist Office is located in the Town Hall of Gérgal, opening from Monday to Friday.

The Festivals in Gérgal are Cabalgata de Reyes Magos, San Sebastián, Moros y Cristianos, Día de Andalucía, Semana Santa, Feria y Fiestas en Honor a la Virgen del Carmen.

Gérgal is home to an interesting castle, constructed in the Lombard style, which dominates the slopes and terraces of the village and, despite being built in the sixteenth century, remains in good condition today. The village has about 1000 inhabitants.
