Immurement is capital punishment by entombing for life.
A famous case has transpired in ancient Rome, where a Vestal Virgin convicted of violating her vows of celibacy was buried alive in a tomb containing a small amount of bread and water, ostensibly so that the goddess Vesta could save her should she have been in actuality innocent.
In the 17th and early 18th centuries in feudal Russia, this mode of punishment was known as "the pit" and used against women who were condemned for killing their husbands [citation needed]. The last known case of this occurred in 1740.
