History
Castillejos was founded as a pueblo in 1743. The earliest families to settle in the town were Tagalogs. Until January 23, 1863, it was known as Uguit. How it was renamed Castillejos is still a matter of conjecture. The most probable reason was the victory of the Spaniards against the Moroccans in a war that took place in Castillejos, Morocco in the year 1860.
The earliest known leader of Castillejos was Don Ignacio de San Agustin who most probably ruled the pueblo in the late 18th century.
In 1950, Castillejos was formally organized as a separate municipality.
Economy
Castillejos is an agricultural town where rice is the most important crop. Mango is the primary fruit being produced. Some farmers raise vegetables, hogs, poultry and eggs to supplement their income. At the town center, small traders and shop owners cater to the daily needs of the residents.
