The town is located in a large valley between high mountains and hills covered with forest and jungle.

Trancas was a strategic point for the defense of the North and witnessed important events during the struggle for Argentina's independence.

The Church of the Sacred Heart (Iglesia del Sagrado Corazón) was declared a National Monument in 1957.

The interior is simple, with a choir as a transition area at the entrance, and behind the chapel of souls.

Inside it preserves a heritage of religious art: the image of the patron saint San Joaquin, (perhaps from a workshop in Upper Peru) a St. Joseph and a Nazarene.
