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.

Basel ( BAH-zəl, German: [ˈbaːzl̩] (listen)) or Basle ( BAHL; French: Bâle [bɑl]; Italian: Basilea [baziˈlɛːa]; Romansh: Basilea [baziˈleːa] (listen)) is a city in northwestern Switzerland on the river Rhine. Basel is Switzerland's third-most-populous city (after Zürich and Geneva) with about 180,000 inhabitants. The official language of Basel is (the Swiss variety of Standard) German, but the main spoken language is the local Basel German dialect.
Basel is commonly considered to be the cultural capital of Switzerland. The city is famous for its many museums, ranging from the Kunstmuseum, the first collection of art accessible to the public in the world (1661) and the largest museum of art in Switzerland, to the Fondation Beyeler (located in Riehen) and the Museum of Contemporary Art (Basel), the first public museum of contemporary art in Europe. Forty museums are spread throughout the city-canton, making Basel one of the largest cultural centres in relation to its size and population in Europe.
The University of Basel, Switzerland's oldest university (founded in 1460), and the city's centuries-long commitment to humanism, have made Basel a safe haven at times of political unrest in other parts of Europe for such notable people as Erasmus of Rotterdam, the Holbein family, Friedrich Nietzsche, and in the 20th century also Hermann Hesse and Karl Jaspers.
