Thanjavur Maratha Palace – Secret Chambers
There
are at least 3 hidden chambers with secret, interconnecting doors. These were
used as torture chambers and to have discreet meetings. One hidden chamber,
located at the base of the Arsenal tower is acoustically designed in a way that
you can hear even the smallest whisper from 3 floors above. This must have been
used as a way for sending secret voice signals over multiple floors. Sadly, the
Government has completely prohibited all access to these hidden chambers.
