500 Year Old Russian Eavesdropping Device

Archaeologists have uncovered a 500-year-old spy chamber beneath a Moscow street. 

It was built underneath a 2.5km wall to protect Russians from Polish raids – and was used to listen in on the enemy through a wall.

It is said the room’s vaulted walls created an acoustic effect which allowed people to eavesdrop.

It contained around 150 artifacts, including ancient cooking equipment, upon its discovery. more with video
