It all started over 150 years ago with the invention of the tin can—a process started by the Frenchman Nicolas Appert and finally patented by Englishman Peter Duran in 1810. That moment saw the birth of a whole new industry. The abundance of high-quality fish, caught along Portugal's extensive coast line, created the natural conditions for the appearance of the country's first canneries.
That status was consolidated by exports, mainly during the First and Second World Wars, making Portuguese canned goods famous around the world as part of a business sector that, at one point, was the second largest in the economy of its day. It was a time that saw Portuguese industry flourish with factories spreading across the country.
