Tourism is also important, and the city has a role as a winter and mountain resort. Fruit production is important in the region of Cova da Beira, a subregion centered in Covilhã's municipality. Frulact, a Portuguese fruit processing company, has major industrial facilities in the municipality of Covilhã. The city has a science park - Parkurbis - which has attracted several new businesses to the area. In the mid-2000s, Aleia (a joint-venture of the French companies Dyn'Aéro and Equip’Aéro with the Portuguese Spinworks and Plasdan) announced its intention to produce jet planes of four and six places integrally conceived, constructed and mounted in Covilhã as from 2011. The existence of the University of Beira Interior, with its degree of aeronautical engineering, as well as the local aerodrome contributed for the final decision from Aleia to develop an aerospace industry in the town. There is a large shopping centre in Covilhã, "Serra Shopping", and besides a wide variety of shops, it has hypermarket, four cinemas and many restaurants. Hypermarkets and supermarkets located in the lower part of the town include Continente (inside "Serra Shopping"), Intermarché, Pingo Doce and Lidl. The Public Market ("Mercado Municipal") is another option and an opportunity to buy fresh produce directly from the producers. This town was recently chosen by the biggest telecommunications company in Portugal Portugal Telecom to there build and install one of the biggest Data Centres of Europe, with the capacity to store 30 petabytes of information. The building, opened in September 2013 has a floor area the size of thirteen football pitches. Covilhã is considered now the biggest town in terms of Development and new technologies. The City Hall of Covilhã used to be responsible for the cultural programming of one of the movie theatres of the town which has a wide variety of activities throughout the year. Such Movie Theater is now closed. There are also various theatre companies: Teatrubi, ASTA, Teatro das Beiras and Quarta Parede that stage theatre and multimedia productions throughout the year. A theatre festival is organised by a local theatre company, Teatro das Beiras, in November. The city hosts several choirs and orchestras, like the well-known university choir and the EPABI orchestra, which is based in the building near the public garden (location has now changed to the lower parts of the city), as well as the "Orquestra da Banda Filarmónica".
