The Cape Matapan Caves, also known as Tenaro or Cape Tainaron,

are located at the southernmost tip of the Greek mainland. 

They have long been associated with the Greek god Hades, the god of the underworld. 

In Greek mythology, it was believed that the caves were one of the entrances to Hades. 

The caves are located at sea level, and they lead into a network of chambers concealed beneath the cliff face.  

Marked by the remnants of a Spartan temple atop the cliff, this particular gateway holds 

unparalleled significance among the various entrances believed to lead to Hades.
