Sonsonate (Spanish pronunciation: [sonsoˈnate]) is a department of El Salvador in the western part of the country. The capital is Sonsonate.
The department has a population of over 463,000 and an area of 1,226 km².
Created on June 12, 1824. The El Salvador National Parliament decided on January 29, 1859 to separate from the department the cities of Apaneca, San Pedro Puxtla, Guaymango and Jujutla and give these cities to Santa Ana Department.
Sonsonate City was the second capital of the Federal Republic of Central America in 1834.
The department remains the heart of the Pipil culture in the country, home to several ancient traditions and to most of the few remaining Nahuatl speakers in El Salvador.
It is an overwhelmingly agricultural area, with extremely fertile volcanic soils that once were the most valuable resource in Central America for the Spanish conquistadors who profited from its ancient cacao plantations. Its name appropriately means "Place of 400 rivers" or "Place of many waters" as it receives well over 2,000mm (79 inches) of rain a year.
The most cultivated agricultural products are the basic grains, coffee, cotton, sugar cane, coconut, fruits, balsam trees, palm, tulle, and orchard plants.
Among the most remarkable manufacturing industries are those of dairy products, panela, sugar, tiles and bricks of mud, clothes, footwear, candles, soaps, and leather articles. Coconut trees are plentiful in the suburbs and thus the city is known poetically by the epithet “the city of the palms”.
The average annual temperature is 25 °C.
