[1] The first church for the parish of Dulce Nombre de Jesús was a simple structure built in 1769.

Dulce Nombre de Jesύs became a cathedral church when Pope Benedict XVI established the Diocese of Fajardo-Humacao on March 11, 2008.

It is flanked by two smaller round towers that house a spiral staircase and the weights for the clock.

The floor is covered with colored native cement tiles and a new choir loft is in the rear of the church.
