Salt is a mineral composed primarily of sodium chloride (NaCl), a chemical compound belonging to the larger class of salts; salt in its natural form as a crystalline mineral is known as rock salt or halite. Salt is present in vast quantities in seawater, where it is the main mineral constituent. The open ocean has about 35 grams (1.2 oz) of solids per liter of sea water, a salinity of 3.5%.
Salt is essential for life in general, and saltiness is one of the basic human tastes. Salt is one of the oldest and most ubiquitous food seasonings, and salting is an important method of food preservation.
Some of the earliest evidence of salt processing dates to around 6,000 BC, when people living in the area of present-day Romania boiled spring water to extract salts; a salt-works in China dates to approximately the same period. Salt was also prized by the ancient Hebrews, the Greeks, the Romans, the Byzantines, the Hittites, Egyptians, and the Indians. Salt became an important article of trade and was transported by boat across the Mediterranean Sea, along specially built salt roads, and across the Sahara on camel caravans. The scarcity and universal need for salt have led nations to go to war over it and use it to raise tax revenues. Salt is used in religious ceremonies and has other cultural and traditional significance.

Málaga (, Spanish: [ˈmalaɣa]) is a municipality of Spain, capital of the Province of Málaga, in the autonomous community of Andalusia. With a population of 571,026 in 2018, it is the second-most populous city in Andalusia after Seville and the sixth most populous in Spain. It lies on the Costa del Sol (Coast of the Sun) of the Mediterranean, about 100 kilometres (62.14 miles) east of the Strait of Gibraltar and about 130 km (80.78 mi) north of Africa.
Málaga's history spans about 2,800 years, making it one of the oldest cities in Europe and one of the oldest continuously inhabited cities in the world. According to most scholars, it was founded about 770 BC by the Phoenicians as Malaka (Punic: ????, MLKʾ). From the 6th century BC the city was under the hegemony of Ancient Carthage, and from 218 BC, it was ruled by the Roman Republic and then empire as Malaca (Latin). After the fall of the empire and the end of Visigothic rule, it was under Islamic rule as Mālaqah (Arabic: مالقة) for 800 years, but in 1487, the Crown of Castille gained control in the midst of the Granada War.
