Little is known about the history of the town but information taken from the old residents revealed that in the latter part of the Spanish regime, this town was a small fishing village north of Ragay Gulf at the mouth of Kilbay River.   A little further to the north was a virgin forest that attracted much the attention of the Spanish traveler Don Juan del Gallego.   Don Juan tried his luck in this unknown land.   He erected his first lumber mill in sitio Pinagdacpan, about five kilometers up Kilbay River.   In a few years, this lumber camp became a progressive community.   The old man also erected a school, a chapel, and organized an orchestra.

     In 1927, the lumber mill was moved to Danawan which is the original name of Del Gallego.   This was done to meet the growing expansion of the people.   A much bigger mill was also erected.

     This town was established through Executive Order No. 56 issued by President Manuel L. Quezon through the efforts of Don Juan Del Gallego and Hon. Francisco Celebrado, assemblyman for the first district of Camarines Sur, who lobbied for the erection of Del Gallego as an independent town from Ragay.

     The parish church was built in 1958 through the efforts of Very Rev. Fr. Antolin Toralba who was then the parish priest.

Kami, sa Parokya ni Santa Rita de Cascia, Del Gallego, Camarines Sur, sagana sa mga yamang kalikasan, kabukiran at karagatan at mga taong may adhikain tungo ssa pag-unlad at kapayapaan, mga minanang kaugalian at pananamplataya sa maykapal.

Subalit kami ay nag-aalala sa maraming naghihikahos dahil sa pagsasamantala ng makapangyarihan, salat sa kaalaman at kasanayan, pagkakawatak-watak at takot dahil sa hindi makabayang simulain, kapabayaan sa tungkulin at pagsasabuhay ng pananampalataya.

Sa pagmamahal ng Diyos, na siyang kaganapan ng lahat, kami ay naghahangad ng bagong simbahan, isang sambayanang buhay kay Kristo na maalab ang pananampalaya, mga tao na maunlad at mapayapa ang pamumuhay, pantay-pantay, nagdadamayan at nagkakaisa sa simulain, tapat sa paglilingkod at nangangalaga sa kalikasan.

Upang ganap na maisakatuparan ang aming pananaw sa kalinga ni Birhen Mariang aming Ina, at ni Santa Rita de Cascia, aming huwaran, ay buong pusong inihahandog  ang aming sarili sa:

-maka-Kristiyanong paghubog tungo sa pagbuo ng mga munting sambayanan na nakaugat kay Kristo

-na nagsisikap sa mga gawaing pangkabuhayan at pangkalikasan, na nakikipag-ugnayan sa mga taong tapat sa panunungkulan tungo sa kaunlaran.
