Torre del Reloj (Puerta del Reloj)

The gate standing today replaced an earlier one. In 1704 the military engineer Juan de Herrera y Sotomayor began repairing the 1631 Puerta del Puente, which had led onto a wooden bridge dating from 1540. That bridge crossed the Caño de San Anastasio, a seawater channel that once separated the walled island of Calamarí from Getsemaní [Wikipedia, Puerta del Reloj]. The work Herrera carried out between 1704 and 1738 is what gives the gate its current form, a Postclassic facade with a Roman arch flanked by Tuscan columns, a style that echoes the Monasterio de San Francisco in Santo Domingo [Wikipedia, Puerta del Reloj].

The original 1631 gate was partly destroyed by the French privateer Bernard Desjean, Baron de Pointis, during his 1697 raid on Cartagena [Wikipedia, Puerta del Reloj es]. What Herrera rebuilt afterward is considered, among specialists, one of the most successful works of the Spanish-American Fortification School and one of the best-preserved gates in the Americas, because it strictly follows the design principles of the Vauban school of fortification [Wikipedia, Torre del Reloj es].

Locals in Cartagena still call this gate Boca del Puente, the Mouth of the Bridge, a name that survives from the drawbridge that once stood at this spot. That drawbridge did double duty as a defense: in the event of an attack, it could be raised to block pirates and buccaneers from reaching the city, working alongside the bastions of San Pedro Apóstol and San Juan Bautista that once flanked the gate [Wikipedia, Puerta del Reloj].

The name most visitors know, Puerta del Reloj or Torre del Reloj, comes from the clock added to the top of the tower in the early 18th century. Before the clock, this was simply the city's main gate, the point where the Isla de Calamarí, the walled core of Cartagena, connected to Getsemaní across the water. Today both names point to the same structure, and either one will be understood locally.

The gate sits between two plazas that tell different parts of Cartagena's story. On the walled-city side is Plaza de la Independencia, and on the Getsemaní side is Plaza de los Coches, a triangular square that was once the city's slave market, one of the largest in the Americas during the colonial period. Today it's lined with arcaded buildings and vendors, a working plaza rather than a memorial, and the gate's arch frames the view straight through it.

Look at the facade itself for the half-point Roman arch and its two pairs of Tuscan columns, the entablature with a triglyph-decorated frieze, and the clock that gives the gate its everyday name. None of the tower's interior is open to the public, so there's no line to skip and no ticket booth to look for, unlike Cartagena's paid monuments such as Castillo San Felipe. The whole visit here is the walk-through and the look up, not an indoor tour.

The gate is also lit at night, and the facade reads differently after dark, the arch and columns picked out against the surrounding buildings, a detail worth a second look if you pass through on your way to dinner in Getsemaní. Photographers tend to shoot it either early morning, before the plazas fill with vendors and tour groups, or after sunset, when the crowd thins and the lit stonework has the frame mostly to itself.

The gate sits at the edge of the historic center, an easy walk from almost anywhere inside the walled city and from most of Getsemaní. Most visitors pass through it more than once a day without planning to, since it's the natural route between the two neighborhoods, and several walking tours either start or pass through here as their first stop.

If you're arriving by taxi or rideshare, ask to be dropped at Plaza de los Coches or Plaza de la Independencia rather than naming the gate itself, since drivers know both plazas by name. From either plaza, Torre del Reloj is a few steps away, and the rest of the walled city opens out from there.
