Historians say that pillories were introduced in Iberia by Romans.
They are formed by a column of stone, placed in public square,
where punishments to convicts took place. These punishments were since several
ways of torture until death by sword or gallows.
This way to apply justice had taken place, in Portugal, since its early days (XII cent.) almost until the end of monarchy (XIX cent.).
Pillories are still an emblem of municipality power.
They have several forms and reflect the architectonic style of the time at which they were built.
