As early as 1760 there were people already settled in Patillas however it was not a permanent settlement. During the mid-18th century there were a lot of people already living in Patillas. Patillas is along the southeastern coast of the island of Puerto Rico. During this time frame, there was an establishment of a sugar cane mill which took advantage of the agricultural potential the valley provided. As this establishment provided a good source of income for the neighbors it also was the main reason for the town's foundation in 1811. Doña Adelina Cintrón, owner of "La Finca Patillas", donated almost 8 acres (32,000 m2) of land for the foundation. Most of the neighbors then relocated towards the west side of the proposed site called Cacao Bajo.
The flag of Patillas has four green rectangles on the corners that symbolize the valleys and mountains of the town. These rectangles are separated by a golden cross symbolizing the fidelity towards the town's religious patron "El Santo Cristo de la Salud". Superimposed in the middle of the golden cross is an emerald, thus the nickname "La Esmeralda del Sur".
The art design of the flag was a creation of Pedro de Pedro in 1977. Each symbol on the flag was defined by Pedro J. Rivera Arbolay. The legal assessor was the attorney Roberto Beascochea Lota.
The coat of arms features a crow with a piece of bread in its beak, which represents the bird that saved the life to San Benito Abad, patron of the town, from being poisoned with a piece of bread. The castle with three windows symbolizes the captivity of Santa Barbara, matron of Patillas in the first years of the foundation and the devotion to the Holy Trinity. The cross represents Santo Cristo de la Salud. The two crossed machetes underneath the cross represent the peasants' struggle in the sugar cane plantations and the origins of economic development. The three towers in the superior part mean that Patillas is categorized as a town. The watermelon leaf, fruit that abounded in the west of Patillas, is the reason for the name of the town. The motto "Ora et Labora", means "Pray and Work"; motto of the religious order of San Benito Abad.
The name Patillas is originally an indigenous name for a native type of watermelon. The large abundance of this fruit in the area, along with the land donation from the original owner, lead to the town's name.
Despite being located in the region known as the Coast Valley of the South, a part of the town is mountainous. The Sierra de Cayey borders the town's territory through the northern region, and the Sierra de Guardarraya through the east.
There are several rivers and creeks that flow through the town of Patillas. There is also the Patillas Reservoir which was built in 1914. The Patillas and Marín Rivers flow into the reservoir which is also used for fishing.
