The fishing village of Punta Santiago was originally called
Playa de Humacao as it was the closest beach to
Humacao Pueblo, the historic and administrative downtown area of Humacao. The community of Punta Santiago used to be part of two former barrios of Humacao, one called Humacao Playa and the other called Mabú. By the end of the 19th century barrio Mabú had been eliminated and incorporated into barrio Playa, now renamed Punta Santiago after the geographical
headland or
point (
punta) where the fishing village is located. Since December 1938,
Cayo Santiago, located immediately off Punta Santiago, has been the home to a population of free roaming
Rhesus macaques imported from
India by the
School of Tropical Medicine in
San Juan, the
Columbia University College of Physicians and Surgeons and the
University of Puerto Rico. The area where the Humacao nature reserve is located today saw a number of bunkers and defensive infrastructure built during the
Second World War, including a lookout post at the top of
El Morrillo hill. This area which contains a number of
mangrove and
Pterocarpus forests was later proclaimed a wildlife refuge in 1986.
Hurricane Maria Hurricane Maria hit Puerto Rico on September 20, 2017. The
hurricane eye entered the island close to
Punta Yeguas in
Yabucoa, not far from Punta Santiago. The barrio was particularly vulnerable to the associated
storm surges. According to Father José Colón, the local Catholic priest, the hurricane caused the total flooding of Punta Santiago. Punta Santiago was one of the most impacted communities in the aftermath of the hurricane. It was the location of the viral image of an
SOS message written on one of the roads of the community. The Punta Santiago Vacation Center was greatly affected by the hurricane, and it remained abandoned by 2023. Puerto Rico National Guard (36673449844).jpg|PR National Guard clearing debris at Punta Santiago after
