A concierge (French pronunciation: [kɔ̃sjɛʁʒ]) is an employee of an apartment building, hotel or office building who serves guests, with duties similar to those of a receptionist. The position can also be maintained by a security officer over the graveyard shift. A similar position, known as the portero, exists in Spanish-speaking regions. In medieval times, the concierge was an officer of the king who was charged with executing justice, with the help of his bailiffs. Later on in the 18th century, the concierge was a high official of the kingdom, appointed by the king to maintain order and oversee the police and prisoner records.
