Hidden Architecture of Castillogrande: 5 Modernist Gems

Introduction to the Modernist Legacy of Castillogrande

If you walk through Castillogrande today, you see towers of glass and concrete rising like fingers towards the Caribbean sky. But if you look closely, among those modern masses, there are ghosts of an era when architecture not only protected from the sun but also told stories. I'm talking about tropical modernism, that style that between the 1950s and 70s turned Cartagena into a design laboratory. And Castillogrande, with its constant breeze and land reclaimed from the sea, was the perfect canvas. Here I'm going to take you through five gems that many overlook, buildings that aren't in the tourist guides but are pure memory in brick and cement.

The first thing you need to know: Caribbean modernism is not the same as that of Brasilia or Miami. Here, architects played with light, wind, and humidity. They used latticework, overhangs, and colors that blend with the landscape. And in Castillogrande, that legacy is more alive than it seems, even if it's sometimes hidden by "For Sale" signs or neglected facades. In May 2026, when the sun beats down hard and the neighborhood fills with tourists looking for beach and partying, it's worth stopping, looking up, and seeing with different eyes.

Here I'm not going to give you a list of cold facts. I'm going to tell you how to find each building, what to look for in their details, and why they are important. And if you're an architect, a student, or simply a curious person, this will help you put together your own walking route, without rushing and with your phone ready for photos that aren't the typical ones on the boardwalk.

What to Do: The Walking Route of the 5 Modernist Gems

Forget the car or the motorcycle. Castillogrande is meant to be walked, especially if you're after architecture. The idea is to start early, before 10 in the morning, when the sun hasn't yet melted everything. Bring water, a cap, and a notebook if you're the type to jot things down. Here's the order I recommend, from north to south, so you don't have to backtrack.

1. Edificio Bahía (Carrera 1 con Calle 7)

This is the grandfather of modernism in Castillogrande. Built in 1958 by Cartagena-born architect Manuel José Martínez, Edificio Bahía is an apartment block that seems to float on stilts. The facade is full of concrete latticework that filters the sun but lets the breeze through. If you stand on the corner of Carrera 1 and Calle 7, you'll see how the shadow changes depending on the time. A curious fact: Martínez was inspired by the stilt houses of the Ciénaga de la Virgen but gave it a modern touch. Today the building is a bit run-down, but its structure remains a lesson in how to build for the tropics.

Where to look: The main entrance has a ceramic mural that many ignore. These are handmade pieces, with blue and green tones that mimic the sea. Don't touch, just look.

2. Residencias El Parque (Calle 8 #1-23)

Half a block from the Parque de Castillogrande, this set of twin towers was designed in 1965 by architect Germán Samper, one of the greats of Colombian modernism. Samper worked with Le Corbusier in Bogotá, but here he adapted to the coastal climate. Residencias El Parque have cantilevered balconies that look like hanging boxes, and the exposed brick facades contrast with the white columns. The most impressive thing is the play of light that forms between the blocks: at noon, the shadows draw geometric patterns on the lobby floor.

Practical tip: The building is private, so you can't enter. But from the sidewalk on Calle 8, you have a perfect view. Bring a wide-angle lens if you want to capture the symmetry.

3. Edificio Mediterráneo (Avenida Miramar #2-15)

This is my favorite. Built in 1962 by architect Rafael Obregón, the Mediterráneo is an example of how modernism can be elegant without being ostentatious. The facade has horizontal concrete bands that resemble waves, and the windows are enormous, designed for the wind to flow from one side to the other. Obregón was known for using local materials, like the quarry stone you see at the base of the building. Today it functions as apartments and offices, but if you peek into the entrance hallway (it's public up to the reception), you'll see an abstract stained glass window representing the Caribbean sun.

Curiosity: Old neighbors say that Obregón used to sit on the sidewalk drawing while the workers raised the walls. The building took three years to finish because the architect changed details on the fly.

4. Conjunto Residencial La Playa (Carrera 2 #5-10)

This complex of three towers, completed in 1971, is the youngest on the list. It was designed by the firm Cuéllar Serrano Gómez, which also did el Centro Internacional de Bogotá. Here the novelty is the use of the "brise-soleil" or sunbreakers: concrete screens that rotate according to the sun's position. If you stand in front of the central tower at 4 in the afternoon, you'll see how the shadows move as if the building were breathing. Additionally, the internal gardens have palms and native plants that landscape architect Fernando Martínez designed to grow without artificial irrigation.

Warning: The complex is residential and has security. Don't try to go past the entrance. But from Carrera 2, at the traffic light, you have a complete view of the three towers.

5. Casa del Arquitecto (Calle 6 #3-45, esquina con Carrera 3)

This is not a giant building, but a private house built by architect Luis Guillermo “Willy” De la Vega in 1968 to live in with his family. It's a hidden gem because it has no plaque or sign, and only the neighbors know it's there. The facade is a play of inclined planes and angled windows, with a roof that looks like a frozen wave. Willy De la Vega was known for his organic designs, combining modernism with forms inspired by the sea. The house is on a corner, so you can see it from two streets. That said, it's private, so no flash photos or peeking into the garden.

Key fact: The house has an internal patio with a kidney-shaped pool, typical of the 1960s. It's not visible from the street, but if you ask an older neighbor, they might tell you stories about Willy's parties.

Where to Eat or Drink: Breaks Along the Route

After walking for a couple of hours, hunger and thirst set in. Castillogrande isn't a neighborhood full of tourist restaurants, but it has local options worth trying. Here are three recommended stops, all close to the route.

El Café de la Esquina (Calle 7 #2-50)

A small place with tables on the sidewalk. They serve black coffee with pan de bono and meat empanadas. The owner, Don Carlos, has been there for 20 years and knows everything about the neighborhood. Ask him about the old buildings and he'll tell you stories you won't find online. Open Monday to Saturday, 7am to 7pm. A black coffee costs about $2,500 COP (reference prices from May 2026).

La Perla del Caribe (Avenida Miramar #3-12)

A restaurant serving coastal cuisine, with dishes like rice with coconut and fried fish. The place has a terrace with a sea view, ideal for resting after seeing the Edificio Mediterráneo. Prices range from $25,000 to $45,000 COP per dish. Open Tuesday to Sunday, 12pm to 9pm. It is recommended to verify hours before visiting.

Heladería La 8 (Calle 8 #1-50)

An artisanal ice cream stand with flavors like corozo, tamarind, and coconut. Perfect for cooling down between buildings. A double cone costs $4,000 COP. It's open every day from 10am to 8pm.

How to Get There and Transportation

Getting to Castillogrande is easy from any point in Cartagena. If you're in the Centro Histórico or Bocagrande, you can walk (it's about 20 minutes from the Torre del Reloj along Avenida San Martín). But if the sun is strong, it's better to take a taxi or Uber: the trip from the Centro costs between $8,000 and $12,000 COP (reference prices from May 2026). There are also city buses that pass along Avenida Miramar, like the T1 route that goes to Castillogrande. The fare is $2,600 COP.

For the walking route I propose, it's best to start at Edificio Bahía (Carrera 1 con Calle 7) and end at Casa del Arquitecto (Calle 6 #3-45). The full walk, with stops for photos and rests, takes about 2 and a half hours. Wear comfortable shoes because the sidewalks have uneven surfaces and holes.

Local Tips

• Ideal time: Start at 8am. This way you avoid the strong sun and the streets are quiet. The buildings look better with the morning light.
• Photos without intruding: Don't use flash or get close to the windows. The neighbors are friendly but don't like having their homes photographed. Use a 50mm lens or zoom from the sidewalk.
• Talk to the doormen: The building porters often know historical facts. If they take a liking to you, they might let you see the lobby. A "good morning" and a smile open doors.
• Bring a printed map: The internet sometimes fails in Cartagena, especially near the sea. Download an offline Google Maps map or print the route I give you here.
• Don't limit yourself to the 5: While you walk, you'll see other modernist houses and buildings not on the list. If something catches your eye, note the address and look it up later. Part of the fun is discovering on your own.
• Share on social media: If you find a hidden gem, post it with the hashtag #CastillograndeOculto. That way, together we can build a collaborative map.

Frequently Asked Questions

Can I enter the buildings to take photos?

Most are private residences. You can only access common areas (like the lobby of Edificio Bahía or the entrance of the Mediterráneo) if the doorman gives you permission. Don't insist if they say no. The best photos are taken from the street, respecting the residents' privacy.

Are there guided architecture tours in Castillogrande?

There are no permanent official tours, but occasionally the Faculty of Architecture at the University of Cartagena organizes free tours open to the public. It is recommended to follow their social media or ask at the tourism office in the Centro Histórico. You can also hire a private guide, but it's expensive (from $150,000 COP).

What other neighborhoods in Cartagena have similar modernist architecture?

Bocagrande has several buildings from the 1950s and 60s, such as the Edificio Chambacú or the Hotel Caribe. Also, the El Laguito neighborhood preserves modernist houses, although many have been demolished to build new towers. If you're interested in the topic, I recommend walking along Avenida San Martín in Bocagrande and looking for buildings with latticework and overhangs.

And that's it. Next time you pass through Castillogrande, don't just focus on the boardwalk and the shops. Look up, gaze at the facades, and let those buildings tell you their story. If you find any gem I didn't mention, don't keep it to yourself: share it with the hashtag #CastillograndeOculto. Together we can build the definitive route of Caribbean modernism.
