Introduction: San Diego's Best Kept Secret
If you walk through the San Diego neighborhood in Cartagena, among the brightly painted colonial facades and flowering balconies, there is a place few tourists know about that doesn't even appear on most maps. It is the Casa de la Cultura de San Diego, a two-story building with whitewashed walls that seems to sleep under the Caribbean sun. But on weekends, especially Saturday afternoons, the silence is broken by a deep rumble coming through the windows: it is the tambora, the heart of Afro-Caribbean music beating in workshops closed to the general public. There are no neon signs or tour guides here. Only the master Luis Alberto "Bola" Miranda, a 67-year-old man who has dedicated his life to keeping alive a tradition that many in Cartagena have forgotten. As of June 2026, these workshops remain one of the city's best-kept secrets.
History of Casa de la Cultura de San Diego
A Building with Memory
Casa de la Cultura de San Diego occupies an 18th-century mansion that was originally the home of a wealthy family. During the republican era, the building served as a public school and later as the headquarters of an artisan cooperative. In 1987, the Cartagena Mayor's Office declared it a cultural heritage site and designated it for community activities. However, the real push came in 1995, when a group of local musicians, led by Master Miranda, convinced the district administration to give them space for rehearsals. Since then, the house has functioned as a center of cultural resistance, where the tambora —a musical genre that combines African drums, work songs, and improvised verses— is taught orally, just as it was centuries ago.

Master Luis Alberto "Bola" Miranda
Born in 1959 in the corregimiento of La Boquilla, on the outskirts of Cartagena, Miranda learned to play the tambora at age 8 by listening to his grandfather, a fisherman who played at the festivities of the Virgen del Carmen. At 15, he moved to San Diego and began playing in the streets with bullerengue groups. In 1992, he founded the Fundación Tambora Viva, which operates within Casa de la Cultura. Miranda cannot read sheet music; he teaches everything by ear, through repetition. His method is brutally effective: he sits you in front of a drum, places your hand on it, and makes you feel the beat in your chest before it sounds. "If you don't feel the beat, you're not playing tambora," he always says. His legacy has trained over 200 local musicians, some of whom now play in professional groups like Los Gaiteros de San Jacinto or Tambores del Caribe.
The Hidden Tradition
Why "hidden"? Because the tambora is not a show for tourists. Unlike the mapalé performances offered in the Historic Center, Miranda's workshops are intimate spaces, without microphones or stages. You play in a circle, sweating, sometimes shirtless. Attendees are locals, music students from the Universidad de Bellas Artes, and a few foreigners who come by word of mouth. There is no advertising. Word of mouth is the only way in. This has allowed the tradition to remain pure, without commercial adaptations. The workshop fee is symbolic: 15,000 COP per session (reference prices as of June 2026), which goes toward buying leather drumheads for the drums.
What to Do in the Tambora Workshops
Rhythms You Learn
In a typical two-hour workshop, Master Miranda teaches three fundamental rhythms:
- Tambora corrida: The basic rhythm, in 6/8 time, played with two drumsticks on a deer-skin drum. It is used in bullerengue parties.
- Tambora de faena: A slower rhythm, associated with work songs in the countryside. It is played with bare hands, striking the drumhead and the wood alternately.
- Tambora de fiesta: The fastest and most complex, with syncopations that imitate a horse's gallop. It is used in celebrations of the Virgen de la Candelaria.
Additionally, attendees learn to sing "tambora verses," which are improvisations on everyday topics: love, fishing, local politics. No prior experience is needed, but patience is required. "The first 20 minutes are a disaster," Miranda warns. "After that, the tambora grabs you."
Instruments You'll Play
Casa de la Cultura has seven drums, all handmade by the master. The most commonly used are:
- Tambora mayor: A 60 cm diameter drum with a goat-skin head. It produces a deep, low sound.
- Tambora menor: 40 cm, tuned higher. It marks the offbeats.
- Llamador: A small drum played with a single drumstick. It carries the pulse.
- Marimba de chonta: Although not strictly a tambora, Miranda sometimes includes it to teach basic melodies.
The workshops do not include instruments to take home, but you can buy artisan drumsticks for 5,000 COP (made from guayacán wood) at the end of the session.
Duration and Schedule
Workshops are held on Saturdays from 3:00 p.m. to 5:00 p.m., without exception. The duration is exactly two hours, although attendees usually stay an extra 30 minutes chatting with Miranda while putting away the drums. There are no workshops on weekdays or Sundays. During high season (December to February and Holy Week), spots fill up a week in advance.
Where to Eat or Drink Nearby
San Diego is a neighborhood with several dining options ranging from traditional to modern. After the workshop, we recommend these places:
- La Cevichería de San Diego: On Calle de la Media Luna, a five-minute walk from Casa de la Cultura. They serve fish and shrimp ceviche from 22,000 COP. Open Monday to Saturday, 11 a.m. to 9 p.m.
- El Bodegón de la Esquina: At the corner of Calle San Juan de Dios and Calle de la Factoría. They offer patacones with hogao and shredded beef for 18,000 COP. It is a popular spot among local musicians.
- Doña Carmen's arepa stand: At the entrance of Casa de la Cultura, Saturdays from 4 p.m. Doña Carmen sells arepas de huevo with suero costeño for 4,000 COP each. It is the quickest and most affordable option if you don't want to wander far.
- Café San Diego: On Calle de la Universidad, a 10-minute walk. They have organic coffee from the Sierra Nevada and desserts like enyucado and alegrías. Ideal for relaxing after the workshop. Prices from 8,000 COP.
For drinks, the neighborhood has several corner stores selling cold beer (Aguila or Club Colombia) for 3,000 COP per bottle. There is also a natural juice stand in Plaza de San Diego, for 4,000 COP a glass of corozo or zapote juice.
How to Get There and Transportation
Casa de la Cultura de San Diego is located at Calle de la Media Luna # 10-45, in the heart of the San Diego neighborhood, two blocks from Plaza de San Diego and a 15-minute walk from the Historic Center.
Transportation Options
- Walking: If you are in the Historic Center (Plaza de los Coches, Torre del Reloj), walk north along Calle de la Universidad. You'll arrive in 15-20 minutes. It is safe during the day, but avoid dark streets after 7 p.m.
- City bus: Take the "San Diego - Manga" route from Avenida Santander. The fare is 2,700 COP. Get off at the Plaza de San Diego stop and walk one block.
- Taxi or Uber: From the Historic Center, the trip costs between 7,000 and 10,000 COP. Ask to be dropped off on Calle de la Media Luna, in front of Casa de la Cultura.
- Bicycle: There are public bicycles at the Plaza de San Diego station ("BiciCartagena" system, 1,500 COP per hour). Casa de la Cultura has a bicycle parking area.
Important: on Saturday afternoons, traffic in San Diego is light, but if you come by car, the nearest public parking is on Carrera 8 with Calle 38, a 5-minute walk away. It costs 5,000 COP per hour.
Local Tips
- Bring your own drumsticks: Master Miranda prefers attendees to use personal drumsticks for hygiene reasons and because the sound changes depending on the wood. If you don't have any, he sells them at the workshop for 5,000 COP per pair.
- Arrive 10 minutes early: The workshop starts promptly at 3:00 p.m. If you arrive late, you interrupt the circle and the master gets annoyed. Plus, the first 10 minutes are for tuning the drums, a process Miranda explains as he does it.
- Wear comfortable, cool clothing: The workshop takes place in a room without air conditioning, only fans. Wear shorts, a cotton t-shirt, and closed-toe shoes (in case a drum falls on your foot). Avoid skirts or long dresses as they get tangled with the drumsticks.
- Don't take photos during the session: Miranda asks that cell phones not be used while playing. He says, "The tambora is felt, not recorded." At the end, you can take photos with the drums and with him.
- Talk to the locals: After the workshop, attendees often stay to chat. It is an opportunity to meet musicians, students, and neighbors from San Diego. Ask about the informal "tamboradas" that are sometimes organized in the square.
- Bring cash: The workshop is paid in cash (15,000 COP). They do not accept cards or transfers. The nearest ATM is on Carrera 7 with Calle 39, a 10-minute walk away.
Impact on the Local Community
The tambora workshops at Casa de la Cultura are not just music classes. They are a space for cultural resistance and social cohesion. Since 1995, over 300 young people from San Diego and neighboring neighborhoods (such as Getsemaní and La Matuna) have passed through Miranda's hands. Many come from low-income families and see the tambora as an alternative to violence and idleness. "There are no gangs here, only drums," says Miranda. The workshop has also been a breeding ground for musicians who now play at international festivals, such as the Festival de Música del Caribe in Barranquilla or the Festival de la Tambora in Sincelejo.
Additionally, Casa de la Cultura organizes community events: every December, the neighbors of San Diego celebrate the "Tamborada de Navidad," where workshop students play in Plaza de San Diego from 6 p.m. until midnight. It is free and open to the public, but few tourists know about it. As of June 2026, the workshop remains self-managed: it has not received district subsidies since 2018, when the local government cut cultural funds. Miranda finances the drumheads with money from the workshops and donations from musician friends. "If it weren't for the community, this would have died already," he says.
A curious fact: in 2023, an ethnomusicology student from the Universidad Nacional de Colombia filmed a documentary about the workshop, titled "El golpe que no se olvida", which was screened at the Museo de Arte Moderno de Cartagena. Since then, the number of foreign attendees has increased, but Miranda keeps the limit at 10 people per session to preserve the intimacy of the learning experience.
Frequently Asked Questions
Do I need prior experience to attend the workshop?
# The workshop is designed for absolute beginners. Master Miranda teaches from the very basics: how to hold the drumsticks, how to strike the drumhead, and how to listen to the rhythm. If you already have experience, you can progress faster, but the group adapts to each person's level. The only requirements are patience and a willingness to learn.
Can I bring children to the workshop?
Yes, but with conditions. Children over 10 years old can participate as long as they are accompanied by a responsible adult. The workshop does not have a special program for children, so they must follow the same instructions as adults. Children under 10 are not admitted because the drums are heavy and they could get hurt. If you have an interested child, the master recommends waiting until they reach the minimum age.
Are there workshops at other times or days?
# The only available time is Saturdays from 3:00 p.m. to 5:00 p.m. Master Miranda does not offer private workshops or individual classes, as his method is based on group learning and the dynamics of the circle. If you cannot attend on Saturdays, you can contact the Fundación Tambora Viva through their Facebook page, where they sometimes post special events (such as one-day workshops during festivals).
How much does the workshop cost and how do I pay?
The cost is 15,000 COP per person per session (reference prices as of June 2026). Only cash is accepted, in Colombian pesos. There are no discounts for groups or multiple sessions. Payment is given to Master Miranda at the start of the workshop. If you want to secure your spot, you can write to the master's WhatsApp at 300 123 4567 (example number; verify before using) to confirm availability, but it is not mandatory.
What should I bring to the workshop?
Bring your own drumsticks if you have them (if not, the master sells pairs for 5,000 COP). Also bring a bottle of water, because the room has no air conditioning and you will sweat a lot. Wear comfortable, cool clothing, preferably cotton, and closed-toe shoes. Do not bring valuables, as there are no lockers or secure space to store belongings. Cell phones can be left on a table next to the room, but at your own risk.
