The Machín–Ramos Residence (Spanish: Residencia Machín–Ramos) is a historic late 19th-century house located in San Lorenzo Pueblo, the administrative and historic center of the municipality of San Lorenzo, Puerto Rico. The building is the best example of 19th-century Spanish Creole vernacular architecture in San Lorenzo and a good example of this style of architecture in Puerto Rico, with well-preserved examples of this type of building becoming rarer throughout the island in the 20th century.Although the exact date of construction is not officially known, it is very possible based on urban plans that the building existed before 1883, the oldest written documentation of its existence in the form of property titles. The first known owner of the building was Don Pedro Machín y Flores and his wife Cándida Rosa Machín y Parrilla, the former being the daughter of San Lorenzo mayor Don José Machín y Alonso. The Machín family originated from the island of Fuerteventura in the Canary Islands, relating to the Isleño or Canarian vernacular architectural style that inspired this type of residence throughout 18th and 19th-century Puerto Rico.The house has been declared a historical monument by the Institute of Puerto Rican Culture (ICP) and has been listed in the United States National Register of Historic Places since 1989. Today it functions as a house museum and as the headquarters of the Municipal Department of Art, Culture and Tourism of San Lorenzo (Departamento de Arte, Cultura y Turismo de San Lorenzo).

The Church of Nuestra Señora de las Mercedes de San Miguel de Hato Grande (Spanish: Iglesia Nuestra Señora de las Mercedes de San Miguel de Hato Grande), also known as the Church Las Mercedes of San Lorenzo (Iglesia de las Mercedes de San Lorenzo), is a historic Roman Catholic parish church located in San Lorenzo Pueblo, the administrative and historic center of the municipality of San Lorenzo, Puerto Rico. Las Mercedes was named in honor of both the Virgin Mary and Doña Mercedes Delgado Manso, the wife of the then mayor of San Lorenzo and a descendant of Don Sebastián Delgado Manso, one of the founders of the city of Caguas.Although the current structure of Las Mercedes officially dates to 1887, it was built at the site of a former chapel originally named Hermitage of Hato Grande (Ermita de Hato Grande, also known then as La Ermita del Hato) that was built in 1737, at a time when San Lorenzo was a newly settled small village. Records from the Caguas City Hall show that the architecture of that hermitage resembled that of Porta Coeli Monastery Church in San Germán. The original structure of the hermitage was preserved as the foundation of the current church, with the current nave and the Neoclassical belltower being added to that original structure in 1814 and in 1876 respectively. The hermitage was upgraded in size with the current walls and façade finally being added in 1887 by state architect Pedro Cobreros. The church is one of the best examples of late 19th century Neoclassical architecture that would set a trend in the religious architecture in the island, and for this reason it was added to the National Register of Historic Places in 1983.
