Getsemaní & San Felipe Castle Walking Tour in Cartagena

Two Neighborhoods, Three Centuries of History

A Cartagena walking tour through Getsemaní and San Felipe Castle covers more Colombian history in three hours than most visitors encounter across an entire trip — and it does it in two places that feel nothing like the polished tourism of the walled city.

Getsemaní: The Neighborhood That Remembered Everything

Getsemaní is one of those neighborhoods that took decades to be recognized for what it always was. While the walled city of Cartagena was drawing wealthy visitors and boutique hotels, Getsemaní was quietly preserving something rarer: the daily life of a working community with a long memory and something to say. The murals that cover its streets today are not decoration — they are a running record of the neighborhood’s history, its politics, and its refusal to be overlooked. Your guide reads them as a local, pointing out what each image references and why it was painted where it was. Walking with that context is a completely different experience from passing through on your own.

The neighborhood’s place in Cartagena’s political history is equally significant. Getsemaní played a central role in the city’s declaration of independence from Spain on November 11, 1811 — a date that locals still mark with celebration. Plaza de la Trinidad, where your tour begins, was the gathering point for the community leaders who pushed the declaration forward. Standing in it today, surrounded by vendors, children, and the ordinary movement of neighborhood life, it is easy to miss that significance. Your guide makes sure you don’t.

San Felipe Castle: The Fortress That Was Never Taken

San Felipe Castle — Castillo de San Felipe de Barajas — is the largest Spanish fortress ever constructed in the Americas. Building began in 1536 on the Lázaro Hill, chosen for its commanding view over the bay and the approaches to the city. Over the following two centuries, the fortress was expanded repeatedly, its walls thickened, its tunnels extended, and its cannon positions multiplied, as the Spanish crown recognized Cartagena’s importance as the principal port for silver and gold leaving South America for Spain.

The castle’s most famous moment came in 1741, during what historians now call the Battle of Cartagena de Indias — the largest naval engagement in the Western Hemisphere before the 20th century. British Admiral Edward Vernon arrived with a fleet of 186 ships and an army of approximately 27,000 men, expecting a quick victory over a Spanish garrison that was outnumbered by nearly ten to one. The Spanish commander, Blas de Lezo, had lost an eye, an arm, and a leg in previous battles. He held the fortress. Vernon was forced to retreat after six weeks, having lost more than half his forces to combat and disease. Lezo died three months later from wounds sustained during the siege, largely forgotten in Spain despite the victory. Your guide tells this story with the kind of detail that makes you understand why Cartagena still talks about it nearly three centuries later.

Inside the Tunnels

The tunnel system beneath the castle is as impressive as the military history above it. The tunnels were designed not just for movement but for communication — their acoustic properties allowed defenders to hear the footsteps of approaching forces through the stone floors and walls, giving the garrison an early warning system built directly into the architecture. Walking through them with a guide who understands the engineering gives you a sense of how deliberately every element of San Felipe was designed.

The View from the Top

From the observation points at the top of the fortress, you see what the Spanish commanders saw: the full sweep of Cartagena’s bay, the approach corridors that any naval fleet would have to navigate, and the city itself spread below the walls. On a clear afternoon, the view extends to the Caribbean horizon. It is the kind of perspective that reorganizes everything you have seen at street level.

Who This Tour Is For

This tour is well-suited to travelers who want more than a surface reading of Cartagena. It works for first-time visitors who want the historical foundation before exploring independently, and for returning visitors who feel they missed the city’s deeper story the first time. The combination of Getsemaní’s street-level culture and San Felipe’s military history covers two completely different registers of what Cartagena is — and both are essential.
