CIBA and GuideSofia: Making a Battlefield Legible

On 14 August 1385, a Portuguese army of roughly seven thousand defeated a Castilian force several times its size on the field of São Jorge, near Batalha. CIBA, the interpretation centre on that battlefield, exists so that visitors understand not only what happened but why it still matters. GuideSofia's work turns that interpretation into a route a visitor can walk with a phone in hand.

The partner context

The Centro de Interpretação da Batalha de Aljubarrota (CIBA) is run by the Fundação Batalha de Aljubarrota. It opened in 2008 on a preserved area of the original battlefield and combines three interactive exhibition rooms, a multimedia show, archaeological finds including the bones of combatants, replicas of period weapons, and an outdoor route across the field that shows where the two armies stood.

The battle is one of the founding events of Portuguese independence and of the Anglo-Portuguese alliance, the oldest active alliance in the world. The nearby Mosteiro da Batalha, a UNESCO World Heritage Site, was built to commemorate the victory.

The interpretation challenge

A battlefield is a landscape, not a gallery. Most of what matters is invisible: the eight hundred pits dug in a single night, the position of the Castilian cavalry, the hour in which the outcome was decided. Interpretation has to make the ground legible.

• Explain tactics, politics, and consequences without turning the visit into a lecture.
• Work outdoors across the field as well as inside the centre.
• Serve school groups, families, and history enthusiasts with different depth.
• Connect the centre, the field, and the monastery into one visit.
• Keep legend (the Padeira de Aljubarrota) and evidence clearly distinguished.

The GuideSofia approach

GuideSofia structured the battle as a sequence of fourteen stops that move from the political crisis of 1383 to the field itself and to what came after. The route is written for listening, opens with what the visitor can see, and uses location awareness so that the right stop plays at the right place on the field.

1. Start with the ground: the first stop corrects a common misconception about where the visitor is standing.
2. Build the stakes: the succession crisis, the siege of Lisbon, and a king without a clear right to the throne.
3. Decode the tactics: the numbers, the trap, and the single hour that decided the battle.
4. Name the cost: the unnamed dead recovered by archaeology.
5. Extend the visit: Nuno Álvares Pereira's later life, the monastery, and the alliance that began here.

Publicly visible work

GuideSofia's public catalogue includes the guide Aljubarrota: O Campo da Decisão, with fourteen published stops in Portuguese, and a companion guide to the Mosteiro da Batalha with nine stops.

These outputs demonstrate content coverage and the interpretive model. They do not by themselves establish visitor adoption, satisfaction, or learning outcomes.

What success should measure

• completion of the outdoor route, stop by stop;
• use by school groups and the questions students ask;
• continuation from the field to the monastery guide;
• demand for additional languages from international visitors;
• visitor feedback on clarity of the tactical explanation.
