Conciergerie, Paris

The Conciergerie is a medieval complex that served as both courthouse and prison, beneath the Palais de Justice on the Île de la Cité. Its architecture combines Gothic and neo-Gothic elements. Look at the substantial stonework and the surviving medieval halls: they are remnants of the royal palace once known as the Palais de la Cité, a complex that also included Sainte-Chapelle.

The building’s role changed when royal residence moved elsewhere; its lower spaces gradually became prison quarters, giving the Conciergerie its enduring identity. During the French Revolution, 2,781 prisoners were held here, judged, and condemned before being taken away for execution by guillotine. Marie Antoinette was among them.

She arrived during the night of August 1–2, 1793, and spent 44 days confined here under constant guard. Her trial opened on October 14, 1793, and continued for two days in the former great hall. The revolutionary court held rapid public proceedings here, and verdicts could not be appealed.

The surviving halls therefore connect royal ceremony, judicial power, and the stark prison history that made this place famous. Today, the Conciergerie functions as a museum and national monument.
