Izalco (Pipil: Itzalku)[1] is a town and a municipality in the Sonsonate department of El Salvador.

[2] According to the traditional story from Juan de Torquemada, the last survivor of Tula, Topilzín Acxitl Quetzalcóhuatl II moved to Central America due to the collapse of the Toltec culture in the Anáhuac valley.

More precisely, the izalcans were one of the four branches of the nahuats[3] who settled in the region, along with the cuzcatlecos, nonualcos, and mazahuas.

They were also part of a group of city-states that the Spanish called Tecpán-Izalco, which comprised 15 settlements.

The area was an important producer of cacao (cocoa beans), which was paid as tribute to the presiding authority of the city-states, and also served as money for the acquisition of goods and services such as obsidian and high-quality Guatemalan jade.

The central city was named Tecuzalco or Tecuzcalco, which means "head or capital of the Izalcos".

Its native Pipil peasants were led by Feliciano Ama, who was hanged by government troops on January 28.

It was built prior to 1570, because in this year the parish was very organized according to the civil documents of Caluco.

They have four couples of Tuscan columns and entablatures with classic decorations that divide the two bodies at the same time.

Another lateral access even preserves what is believed to be the original decoration, with Baroque ornaments that look like a flower and leaves.

The interior of the church possesses some original parts, such as the presbytery and the bases of the columns.

The lateral walls are decorated with entablatures in the classic style; the roof is made of wood and iron sheets.
