Province of Castellón

Castellón is the home of Penyagolosa, the highest mountain of the province and the second highest one in the Valencian Community. It is widely considered to be one of the most emblematic Valencian mountains.

The Greenwich Meridian (the Prime Meridian) passes through the province; there are localities with commemorative monuments such as La Pobla Tornesa, Castellón or Almassora (Paseo Marítimo), and in Castellon it intersects the 40th parallel, and the exact point can be visited at the Meridian Park.^[4]

The province has 135 municipalities:

The province is historically subdivided into 8 comarques:

• Alcalatén
• Alt Maestrat
• Alto Mijares
• Alto Palancia
• Baix Maestrat
• Plana Alta
• Plana Baixa
• Ports

As of 2025, the population is 627,620, of which 49.7% are male, and 50.3% are female. Minors make up 16.9% of the population, and seniors make up 20.3%.^[2]

Traditionally, the economy of Castellón has been focused on the production of citrus and vegetables (Nules and Benicarló). Since the 17th century, Castellón has developed an important ceramic and ceramic tile industry (Onda, L'Alcora, Nules, Castellón de la Plana and Vila-real) and nowadays most of the Spanish tile producers are concentrated in the province. Also, furniture (Benicarló and Vinaròs) and chemical industries (Benicarló and Castellón) are present. There is a large oil refinery in Castellón de la Plana.

Traditional industries such as shoe and footwear (La Vall d'Uixó), fishing (Castellón, Vinaròs) and textiles (Vilafranca and Morella), have given way to a service-based economy due to the increasing importance of tourism in the economy of the province.

The province, and in particular its idle large airport, has become a symbol of the wasteful spending prior to the 2008-2014 Spanish financial crisis.
