In 1963 a large factory was opened in Veghel in the Netherlands. This factory has currently the biggest production volume of Mars factories and is even one of the biggest chocolate factories in the world. Most confectionery products for Europe were produced in Slough and Veghel. The two factories in Slough were located on Liverpool Road and Dundee Road; the one on Liverpool Road closed in 2007, with Twix production moving to the Netherlands and Starburst production moving to the Czech Republic.
