San Lorenzo, Puerto Rico

The Town of the Samaritans

Charco Los 7 Chorros San Lorenzo (san lo-REN-zo) is known as the “Town of Samaritans” and the “Samaritan City”. The patron saints of the town are Nuestra Señora de las Mercedes and San Lorenzo, for whom the town is named.

San Lorenzo is located in the eastern part of Puerto Rico. It is bordered on the north by the municipality of Gurabo, on the east by Juncos and Las Piedras, on the west by Caguas and on the south by Patillas and Yabucoa.

This municipality is part of the geographic region called the Caguas interior valley, although in the southeast part there are some of the higher elevations of the Cayey range, which is part of the eastern humid mountains.

The economy of San Lorenzo, originally based on cattle ranching, included later on the cultivation of sugar cane, that was processed in a refinery moved by steam and five oxen which had two stills. In addition coffee and fruit were cultivated. The wood production, that was very rich, had already decayed by the immoderate exploitation of the forests. Today, the economy is mainly revolves around manufacturing. Clothing, leather shoes, and electronic equipment are produced there. In agriculture, raising livestock and growing fruit are also important economic activities.


San Lorenzo was founded by don Valeriano Muńoz de Oneca. The exact date is not certain because the parochial archives of this municipality were lost in a fire and no copies were available. Coll y Toste believes that it was in 1811 and other investigators such as Generoso Muńoz Morales indicates that it was founded between March of 1813 and April of 1814.

It is said that Gregorio Muńoz de Oneca donated forty acres of land. In the XVIII century the San Miguel de Hato Grande ranch was part of the original Hato Grande de los Delgado ranch, enormous extension of land granted by royal decree to a family, and was part of a ward of the an extensive valley which had as headquarters Caguas.

Documents state that as early as 1737 a hermitage was erected by the parish of Caguas, under the tutelage of San Miguel. The church was constructed in 1812, and during the date of the foundation of the town, 1811 or 1813, the original tutelage of San Miguel was changed to San Lorenzo. According to history it is said that this last saint appeared to several neighbors in the fertile valley of the river.

San Lorenzo is known as “”The Town of the Samaritans”” according to the following story; “During the 1920’s, in the Hato de San Lorenzo ward according to journalistic versions of the time and verbal testimonies of people who lived then: multitudes would go to a place in the mountains where a young 12 year old girl lived.

This young girl named Julia Vázquez Torres, according to versions, had supernatural powers that in repeated occasions provided health to needed people. During these undeniable feats only homemade remedies were applied with medicinal plants, minerals and the pure waters of a nearby well, where the young girl took care of the people. With time, the young girl became an adult, but her reputation as a upright person and dedicated to do good accompanied her every day by her life “.

Son tus campos de bellísimo verdor
y tu gente como ninguna
pueblo que guardas en tus suelos
una historia de inmenso valor.

Posees riquezas dignas de admirar
el Río Grande y el Cerro Gregorio.
Vistes de fe y esperanza nuestro ser
cuando hablamos de tu santa montańa.

Oh, Samaritana eres mujer ejemplar
nuestro gran tesoro fue heredar tu identidad.
Orgulloso yo viviré del pueblo que represento
con la frente en alto te diré es mi pueblo
San Lorenzo, San Lorenzo.
