Salt Pans, literally salt pans, are shallow, flat basins carved in limestone, in which salt is produced from sea water. Extensive expanses of flat rock are divided into many small reservoirs, each having a few square meters. Soliny look very picturesque and is one of the tourist attractions.
The technique of salt production is filling the tanks with sea water, which heats up and evaporates under the influence of sunlight. The brine is gradually concentrated until salt crystals begin to precipitate from the solution. The precipitated salt is collected manually and sold for further processing.
Currently existing salins in Zebbug were built in the early nineteenth century and are passed down from generation to generation. According to a local legend, a greedy watchmaker, wanting to make a fortune on salt, set up many salins and built a special shaft so that the sea would fill the pools by itself. Greed was punished: the porous rock absorbed the salt, and the sea got through the shaft to the fields and destroyed the crops.
