About the walk
You will walk through the northern half of old Cartagena—from Plaza Fernández de Madrid along the streets of San Diego to the bastions and the arcade of Las Bóvedas.
The first stretches connect the square, a small church, a theater, and a former convent. Along the way come a marble statue with its final inscription, a cannonball under glass, dismantled theater boxes, and a three-ton slab that returned somewhere other than where it was meant to go. Then the route leads on to Convent of Santa Clara (Hotel Santa Clara) and the northern wall.
The story moves through mistakes, deals, and second uses. It separates city records from convenient memory, and literary plot from a building’s history. Why must a theater be taken apart in order to be preserved? How can a school complaint uncover a row of shops? The answers stay within the walk.
By the end, you will read San Diego along its seams: where a convent became a university, a chapel became a theater, a hospital became a hotel, and a line calculated by an engineer gave way to the sea.
Why this order
Plaza Fernández de Madrid sets the theme of urban memory, while the church on its corner tests it at once in another way—with a preserved witness to the siege. Along Sargento Mayor Street, the route reaches the theater, where miraculous survival gives way to the restorers’ long work. From the theater, the road continues to San Diego Square: the performing arts carry on in the former convent, where music, theater, and painting are now taught. Across the same square, the route moves to Convent of Santa Clara (Hotel Santa Clara) and compares 2 neighboring convents with different modern destinies. From Convent of Santa Clara (Hotel Santa Clara), Curato Street leads to the northern wall—the defense of the entire quarter you have just crossed. The final stretch along the wall runs from the bastions to Las Bóvedas and completes the theme of repurposing: military spaces become a row of shops.
Those interested in literary Cartagena without hunting for fictional addresses Those who enjoy stories of restoration, mistakes, and unexpected new uses Those who want to walk from San Diego’s intimate squares to the northern wall
Those looking only for Cartagena’s main ceremonial squares and most famous facades Those who prefer easy legends without a conversation about slavery and colonial defense
Before you go
Bring water, sun protection, and shoes comfortable for uneven stone. Do not count interior visits as an essential part of the walk: the church follows its parish life, the theater opens for events and organized visits, and Convent of Santa Clara (Hotel Santa Clara) operates as a hotel. During a service, pause the audio in the church and do not approach the altar area. On the bastions, watch the edge of the masonry and strong gusts of wind; after rain, the stone may be slippery. Arrange individual visits to the theater or hotel spaces in advance.
When to go
Choose the morning or the last hours before sunset, when the squares and open fortifications are easier to handle. Take the first section slowly: details at the church and theater are easy to miss. Leave the most time for the 2 convent complexes and the northern wall, where the story asks you to look around and understand the position of the sea, the channel, and the city.
Backup plan
Closed doors do not cancel the route. At Church of Santo Toribio de Mogrovejo, focus on the facade and remember that the main relics remain inside; at the theater, look at the building’s outer shell, which grew out of a chapel; at Convent of Santa Clara (Hotel Santa Clara), work with the convent’s mass and entrance portal without entering private areas. If you cannot climb the wall, continue to Las Bóvedas along the city streets and trace the defensive logic at the arcade: the building’s position between the quarter and the seaward edge can still be read from below.
