Sensuntepeque is located about 83 kilometres (52 mi) northeast of the capital, San Salvador, at an altitude of 820 metres (2,690 ft).

In March 1871, the town was raided by Salvadorian Liberals with Honduran Army backing after Honduras declared war on El Salvador.

[4] During the war in El Salvador, the road between Sensuntepeque and Ilobasco was important for communications in the area, and one or two patrols a day were made with 25-30 soldiers in the mid-1980s.

[5] In 2013, the Archangel St. Michael Catholic School in the El Nazareno colonia added new classrooms and renovated some of the older buildings; this occurred with the financial assistance of the Japanese government.

The move was necessitated by civic construction projects, such as renovation of the bus terminal, and the addition of street signs and crosswalks.

It is situated on the southern declivity of Pelón mountain[8] at an altitude of 820 metres (2,690 ft),[1][9] and covers an area of 306.33 square kilometres (118.27 sq mi).
