Bellamar Caves are a group of caverns of more than 23 kilometers of galleries located in Matanzas province, Cuba. Due to the beauty of its galleries and caverns, the important paleontological findings, as well as a wide range of crystalline processes, were declared a National Monument.

The galleries and passages of the Bellamar Caves are estimated to have begun to form about 300 thousand years ago. According to scholars, the plain in which the caves are located was originally under the sea, forming part of Matanzas Bay.

The Bellamar Caves were discovered by chance in February 1861 when a slave lost his bar by opening a hole in the ground, trying to remove a lime rock. The slave and the foreman imagined that the earth had swallowed the bar.
