The Puerta del Reloj, Torre del Reloj or Boca del Puente is the main city gate of the historic center of Cartagena de Indias, in Colombia and the original entrance of the fortified city. It is located between the squares Plaza de Independencia and Plaza de los Coches. The name "Puerta del Reloj" responds to the clock with which it was crowned at the beginning of the 18th century. While the name of Boca del Puente is due to the fact that during the colonial period, a drawbridge was raised at the foot of the channel of San Anastasio, which linked the walled city to the legendary Getsemaní neighborhood. In addition the bridge served like defense of the city, since in case of enemy attack, this one was raised to prevent the access of buccaneers and pirates.
