The Punta was one of several naturally occurring stone arches or "windows" on the island. However, It was by far the most dramatic and featured frequently on tourism brochures and guide books.
The local tourism industry revolved around the rock formation and marketed itself under the slogan "Guayanilla — The New Window on the Caribbean."
However there were signs that the Punta Ventana rock window's lifespan was drawing to a close. During an earlier minor quake on January 3 part of the eye had already broken off from seismic activity.
"Playa Ventana has collapsed. Today our icon rests in everyone's memory," said Glidden López, a press officer for the local council.
The loss of the arch has come as another blow to the island's struggling tourism industry, which was given a boosted tourism budget of $25m and a Brand USA campaign as a stimulus to help recover from earlier natural disasters.
Puerto Rico as an overseas territory of the United States is home to 3.2million people, many of whom are still living with the consequences of 2017's Hurricane Maria.
The Category 5 storm killed an estimated 2975 people and did billions in damage.
