The Marinha Grande glass manufacturing industry was first established in the middle of the 18th century. The Royal Glass Factory (Real Fabrica de Vidros) was bought by an English entrpreneur William Stephens who developed the factory and the business under the protection of the Marques de Pombal. The wood from the pine forest was used to fuel the factories. The former palatial home of William Stephens now contains the Museu do Vidro da Marinha Grande which houses glassware from the 17th to the 20th century. In 1826, the factory was given to the state and became one of the country's main producers of traditionally made fine crystal.
Marinha Grande is Portugal's biggest glass manufacturer, and it is also the European capital for the moulding industry, with 250 companies operating there, rightfully giving the town the nickname 'The Crystal City'.
The pine forest is an aromatic forest and has waymarked paths for walkers. It has several campsites within it. There is a cycle route from Marinha Grande to São Pedro de Moel on the coast. There are tours around the glass works and to the glass museums.
Hugo Gaspar, notable Portuguese volleyball player was born in Vieira de Leiria.
