Cagayan

Cagayan (/kɑːɡəˈjɑːn/ kah-gə-YAHN, [kagɐˈjan]), officially the Province of Cagayan (Ilocano: Probinsia ti Cagayan; Ibanag: Provinsiya na Cagayan; Itawit: Provinsiya ya Cagayan; Isnag: Provinsia nga Cagayan; Ivatan: Provinsiya nu Cagayan; Gaddang: Provinsia na Cagayan; Filipino: Lalawigan ng Cagayan), is a province in the Philippines located in the Cagayan Valley region, covering the northeastern tip of Luzon. Its capital is Tuguegarao, the largest city of that province as well as the regional center of Region 2 (Cagayan Valley). It is about 431 kilometres (268 mi) northwest of Manila, and includes the Babuyan Islands to the north. The province borders Ilocos Norte and Apayao to the west, and Kalinga and Isabela to the south.

Cagayan was one of the early provinces that existed during the Spanish colonial period. Called La Provincia de Cagayan, its borders essentially covered the entire Cagayan Valley, which included the present provinces of Isabela, Quirino, Nueva Vizcaya, Batanes and portions of Kalinga, Apayao, and Aurora. The former capital was Nueva Segovia, which also served as the seat of the Diocese of Nueva Segovia. Today, only 9,295.75 square kilometres (3,589.11 sq mi) remain of the former vastness of the province. The entire region, however, is still referred to as Cagayan Valley.
