Martos

With a population of over 24,000 people, Martos is the fifth largest municipality in the province and the second in Jaén metropolitan area. Housing lies at the foot of the 1,003-metre (3,290 ft) Peña de Martos, on the western side of the Sierra Sur de Jaén, a subrange of the Baetic System, in the south of the Iberian Peninsula.

As is essentially the case in the entire province of Jaén, the economy of Martos is heavily based on agriculture, specifically the cultivation of the olive tree. With over 22,000 hectares of olive fields (accounting for 85% of the municipality area) and 20 million liters per year, Martos is the largest olive oil producing city in the world, thus earning the nickname of 'Cradle of the Olive Grove'.

Martos is also an important industrial center in inner Andalusia. French global automotive supplier Valeo established a factory in the city in the 1980s, making it the largest business in the province. Moreover, the low-cost fuel sales company Petroprix was founded in Martos in 2013, becoming the fastest-growing energy company of Europe in 2024.
