La Conciergerie on the banks of the River Seine in heart of Paris was originally built as a medieval palace and is the oldest remaining part of the 'Palais de la Cité' the first royal palace in Paris.
It was used as a prison during the French Revolution's
''Reign of Terror' and it was where people were held prior to being taken to the guillotine. It is famously where Marie Antoinette spent her last days awaiting the same fate.
You can catch a glimpse of her in her cell contemplating her fate...
and take a stroll around the small courtyard which was her last taste of 'freedom'.
The Gothic features of the interior of the building are worth the visit alone.
