Picasso's Guernica at the Reina Sofía

Some works of art transcend the canvas and become symbols of an era. Pablo Picasso's Guernica is one of them: painted in 1937 as a response to the bombing of a defenceless Basque town, this oil painting nearly eight metres wide is today the most visited painting in Spain and one of the most important works of 20th-century art. To understand its history is to understand the century that produced it.

The bombing that gave rise to it: Gernika, 26 April 1937

To understand Guernica you have to go back to 26 April 1937, at 4:30 in the afternoon. The small Basque town of Gernika — a historic symbol of the Basque people and the seat of the Juntas Generales de Bizkaia — was holding a busy market day when the skies filled with aircraft. The Condor Legion, a Luftwaffe unit sent by Hitler to support the Nationalist side, together with the Italian Aviazione Legionaria, dropped tonnes of explosive and incendiary bombs on the town for more than three hours.

The result was devastating: more than 70% of the buildings were destroyed. The death toll remains a matter of historiographical debate, with estimates ranging from 150 to over 1,600 people. What is not in dispute is the nature of the attack: Gernika was not a military target but a civilian centre, and the bombing was deliberate. News spread around the world within hours and provoked unprecedented international outrage.

Picasso receives the commission: Paris, 1937

Pablo Picasso had been living in exile in Paris for years. The Spanish Republican Government had commissioned him in January 1937 to produce a large-format work for the Spanish Pavilion at the International Exhibition in Paris. The Málaga-born painter had a blank canvas when news of Gernika reached the French press at the end of April.

What followed was one of the most intense and well-documented creative processes in the history of art. In just five weeks — between 1 May and 4 June 1937 — Picasso executed the painting in his studio on the rue des Grands-Augustins. The photographer Dora Maar recorded the process in a series of photographs that allow us to trace the evolution of the composition from its earliest sketches to the finished work.

The work: dimensions, technique and composition

Guernica is an oil on canvas measuring 3.49 metres high by 7.77 metres wide. Its large scale is no accident: Picasso wanted the work to dominate the space and overwhelm the viewer, making it impossible to take in from a comfortable distance.

The palette is deliberately austere: greys, blacks and whites. In 1937 the world experienced war through black-and-white photographs and newsreels; Picasso transferred that documentary coldness to the canvas. The composition is an organised chaos:

• An electric light bulb shaped like an eye illuminates the scene from above — a cold, indifferent eye, or the eye of the power that watches over everything.
• A bull on the left — an ambiguous symbol that Picasso himself never fully explained — looks on impassively at the scene.
• A wounded horse rears at the centre of the composition, mouth open and body torn apart: the dramatic axis of the painting.
• A mother holding her dead child at the far left, a modern echo of the Pietà.
• A fallen soldier on the ground, with a broken sword and a flower growing up through the rubble.
• Figures fleeing, screaming, burning: horror concentrated within a rectangle.

The visual language is simultaneously Cubist and Expressionist. Bodies are fragmented and recomposed from multiple simultaneous viewpoints, multiplying the sense of violence and disintegration. There is no red blood: the abstraction makes the horror more universal, applicable to any war.

The work's journey around the world

After the close of the Paris Exhibition, Guernica began a long exile. Picasso lent the work for travelling exhibitions across Europe and the Americas, aiming to raise funds for the Republican cause and to spread awareness of what had happened in Spain.

In 1939, as the Republic's fall became imminent and Franco's victory loomed, Picasso deposited the painting at the MoMA in New York on temporary loan, with one explicit condition: the work would not return to Spain until the country had regained its democratic freedoms. For four decades Guernica was the most visible symbol of international anti-Francoism.

Picasso died in 1973, two years before Franco, without seeing the painting in Spain. It was his testamentary heir who, after the dictator's death and the approval of the 1978 Spanish Constitution, accepted the conditions for its return. On 10 September 1981, escorted by the Civil Guard and amid enormous media coverage, Guernica arrived at the Casón del Buen Retiro in Madrid, where it was displayed behind armoured glass.

In 1992, with the opening of the Reina Sofía Museum as Spain's great national museum of 20th-century art, Guernica was moved to its current location: room 206 of the Sabatini building, second floor.

Room 206: the experience today

The Guernica room is an experience in itself. The work fills almost the entire main wall and there is no way to contemplate it without feeling small before it. Around it, the museum displays the 45 preparatory studies and sketches Picasso made before and during the painting's execution, as well as Dora Maar's photographs documenting the process. These materials contextualise the work and allow us to understand the painter's compositional decisions.

The room tends to be busy, especially around midday and at weekends. Arriving first thing — the museum opens at 10 am Monday to Saturday and Sundays — or during the free late-afternoon slots allows you to enjoy it at a more leisurely pace.

Meaning and impact of Guernica

Guernica is not simply a painting about a specific bombing: it is a denunciation of terror as a weapon of war against the civilian population. In that sense its message is permanently contemporary. Since 1937 it has been reproduced on protest posters, T-shirts, street murals and pacifist rallies across the world.

Artistically, it confirmed the definitive political commitment of avant-garde art and demonstrated that abstract language could be just as — or more — powerful than realism in conveying emotion and protest. It influenced entire generations of artists and remains an unavoidable reference in any debate about art and politics.

Practical tips for seeing Guernica

• Arrive early or late. The room is quieter at opening time (10 am) or in the last hours of the day. Avoid 12–2 pm at weekends.
• Give it time. At least 20–30 minutes in this room alone. The preparatory studies are well worth attention.
• No flash. It is forbidden and ruins the experience for others. Flash-free photography for personal use is permitted.
• Follow the chronological route. The museum proposes a route through Collection 1 (1900–1945) that leads naturally to room 206; arriving there after seeing the earlier avant-gardes greatly enriches the visit.
• Book tickets in advance. During high season, timed-entry tickets sell out. Booking online avoids queues and guarantees access.
