The source of the strange booming sound plaguing residents of the northern Greek city of Thessaloniki was finally located on Tuesday.
Nearly every night since December, residents of the city have been jolted awake by the banging noise they describe as deafening, and even otherworldly.
The sound can be heard in many neighborhoods across the city, but is most audible in the area at the intersections of Kifisias and Akropoleos streets.
Agis Papadopoulos, the President of the Thessaloniki Water Supply authority, announced on Tuesday that the sound was coming from routine tuning of the water supply running through the neighborhood of Meteora, where the sound was most prominent.
Representatives from Thessaloniki Water Supply previously assured the public that the noise was not coming from any work being done on its pipes.
Papadopoulos stated that the sound was the result of an anomaly in the water flow through the pipes.
“Imagine that the water flows through the pipes like a wave. If there is some sort of anomaly in the flow, the contact between the water and the pipe can produce a sound. There was no blockage,” he stated.
Previous theories regarding strange sound in Thessaloniki
Previous theories regarding the cause of the sound included seismic and geological phenomena, but Geology Professor Efthimios Lekkas stated on television news channel ANT1 that the noise is not likely to be natural in origin; rather, it likely came from human activity.
Before the source of the sound was uncovered, Gerasimos Houliaras, the Head of Geodynamic Research at the National Observatory of Athens, reassured viewers of the news network ERT that researchers from the Aristotle University in Thessaloniki were conducting tests into whether or not the noise is coming from some sort of geological event or from something mechanical.
Witnesses reported that the sound seemed to be emanating from the Seikh Su, a hilltop forest to the north of the city.
A local resident spoke to ThessToday.gr, expressing his fears regarding the eerie noise in Thessaloniki:
“When we are at the spot where it is especially loud, we feel as if there is someone hitting the earth from the inside. There is a natural gas conductor at the spot. We are all afraid because we don’t know where it’s coming from. There are people who wake up from the noise early in the morning, at 2:00 and 3:00 AM. Yesterday, I myself was awake at 5:30 AM and I heard it.”
Thessaloniki is the second-largest city in Greece
Thessaloniki, Greece’s second largest city and the capital of Macedonia, is both historic and avant-garde.
The ancient city, located in northern Greece, has a rich history stretching from antiquity to the modern era, but is most noted for its importance during the Byzantine period.
During that time, Thessaloniki was a competitor with the great city of Constantinople in terms of its wealth and influence.
It is known today as a student city, because the Aristotle University, one of the best and largest schools in Greece, is located there.
Full of life and young people, Thessaloniki is an ancient city that is always on the cutting edge. Interesting bars, restaurants, and shops line the streets, and pedestrians easily stumble upon ruins from the many periods of the city’s history during their daily walks.
The White Tower is by far Thessaloniki’s most iconic monument.The current 23-meter (75 foot) tall structure was built on top of a Byzantine fortification first mentioned in the 12th century AD.
After the Ottoman Empire invaded and seized control of the city in 1430, the existing tower was built on top of the old Byzantine structure. It connected with the city’s defensive walls, which were unfortunately mostly destroyed in 1866.
Throughout its Ottoman history, the White Tower was called “the Tower of Blood” or “the Red Tower” because of its reputation as a prison in which many were brutally tortured.
