Carolina (Spanish pronunciation: [kaɾoˈlina]) is a city and municipality located in the northern part of Puerto Rico, bordering the Atlantic Ocean; it lies north of Gurabo and Juncos; east of Trujillo Alto and San Juan; and west of Canóvanas and Loíza. Carolina is spread over 12 wards plus Carolina Pueblo (the downtown area and the administrative center of the city). It is part of the San Juan-Caguas-Guaynabo Metropolitan Statistical Area.
Although Carolina is not technically part of San Juan, it is a short distance from San Juan. Along with San Juan, Bayamón, Guaynabo, Cataño, Toa Baja and Trujillo Alto, it is considered to form part of the island's metropolitan area.
Carolina is known as "La Tierra de Gigantes" (land of giants), in honor of one of its inhabitants: Don Felipe Birriel, who was the tallest man in Puerto Rican history, with an unconfirmed height of 2.413 meters or seven feet eleven inches (7' 11") Carolina is also known as "El Pueblo de los Tumba Brazos" (arm hackers town), because in old days, it is said that people resolved their conflicts with a duel. Lorenzo Vizcarrondo founded Carolina in 1857. The city's original name was Trujillo Bajo. It took on a new name when Don Gaspar Martínez, the person who donated the land to establish the municipality, requested that the town be called Carolina in honor of his daughter Carolina de San Juan.
Carolina once was an important center for sugar production. Today, Carolina is Puerto Rico's fourth largest city and is dubbed the Industrial Capital of Puerto Rico for its concentration of factories.
Carolina is bordering the Atlantic Ocean; south of Gurabo and Juncos; east of Trujillo Alto and San Juan; and west of Canóvanas and Loíza. Its rivers are: Grande de Loíza, and Canovanillas.
