In a special report with CNN,  Dominican archaeologist Kathleen Martinez said she believes she has made a significant breakthrough that could lead to the remains of the Egyptian queen Cleopatra.

A series of clues has brought the Dominican closer to believing that the tomb could be in the Temple of Taposiris Magna in northern Egypt. 

"When I came here, I knew what it was, and it was just a matter of digging to prove that which I knew was feasible here," the archaeologist told CNN, referring to the possibility of finding Cleopatra's tomb in the ancient temple of the goddess Osiris.

For nearly 20 years, Martinez has dedicated herself to exploring this temple in search of clues that would lead her to the tomb of the Egyptian queen. 

In November of this year, Egypt's Ministry of Tourism and Antiquities reported that the Dominican's team had discovered a 1,305-meter tunnel at a depth of 13 meters west of the city of Alexandria dating back to Greco-Roman times, according to Excelsior. 

"The tunnel crosses under the road and a resort. And it led us to the Mediterranean Sea. In the first underwater explorations we were able to detect that the tunnel continues under the lake, which opens great expectations of the fact that there could be structures belonging to the same Taposiris Magna temple. And today they are submerged," mentioned Martinez.

Cleopatra was the last ruler of the Ptolemaic dynasty of Ancient Egypt. She committed suicide in 30 B.C., after the death of her lover Mark Antony.
