Foundation and First Mentions
The history of Dorado officially begins in the first half of the 19th century. The town was founded on November 22, 1842, by Governor Santiago Méndez Vigo. Prior to this, the territory was part of the neighboring municipality of Toa Baja. A key figure in the founding process was Jacinto López Martínez, a wealthy landowner who donated land for the construction of the central square and public buildings, becoming the town's first "military lieutenant" (mayor).
Key Factors of Formation
The town's development was driven by a combination of geographical advantages and administrative decisions:
- Geographical Location: The town is situated on the picturesque northern coast of Puerto Rico, near the mouth of the La Plata River. The settlement was named after the golden fish (dorado or mahi-mahi) that were found in abundance in local rivers and coastal waters.
- Political Will: The local elite's desire for autonomy from Toa Baja allowed for the creation of an independent administrative center, which accelerated infrastructure development, including the construction of the church and town hall.
Early Cultural and Economic Characteristics
In its early period, Dorado's economy was agricultural. The region's wealth was based on:
- The cultivation of sugar cane, which was processed at local haciendas.
- Cattle ranching, which played an important role in providing food supplies.
An important cultural and historical monument of that era is Casa del Rey (King's House), built around 1823—even before the town's official founding. Originally, this building served as a guest house for Spanish officials and travelers, and today it stands as a symbol of Dorado's colonial past.
