Light as the common thread of history

Light as a narrative tool

With more than 2,500 m² of exhibition space, the Archaeological Museum of La Almoina integrates the archaeological remains into a contemporary architecture that allows us to understand the urban evolution of the city, from Roman Valentia to medieval Valencia. In this large and continuous space, lighting is conceived as a fundamental narrative tool: it structures the story, hierarchizes the vestiges and articulates transitions between areas. It makes the superimposition of eras understandable and follows for a coherent reading of the whole without the need for additional exhibition materials.

Throughout the whole, light defines scales, delimits areas and builds depth. Precise beams allow details to be isolated – for example, small domestic pieces such as jars or construction fragments – while more open distributions help to understand the spatial structure of the remains. The grazing light raises vertical planes and makes architectural boundaries that are now fragmented perceptible. This enhances the perception of walls, bases or columns without requiring any physical reconstruction. Lighting also acts on the perception of emptiness. In elements such as wells or cavities, the light suggests depth through controlled gradations, avoiding a literal reading and maintaining the atmosphere of the place. At specific points, the introduction of colour accents allows functions to be identified without breaking the overall coherence of the environment.

Thanks to the variety of light distributions – from uniform flooding to very precise light beams such as narrow spot – the Eclipse spotlight allows the light distribution to be adjusted to the spatial narrative: cutting volumes, underlining geometries and isolating details without altering the visual coherence of the whole. Visual comfort is decisive: darklight technology guarantees a glare-free route, favouring a serene and concentrated perception, in which light accompanies the heritage from discretion.

Materiality, perception and conservation

The choice of a warm colour temperature of 2700K reinforces the materiality of the whole, highlighting the tone of the stone and the historical construction elements. This light generates a serene and enveloping atmosphere, which encourages a leisurely read and fosters an emotional connection with the past. Occasionally, the use of blue light accents – using RGBW – makes it possible to identify and differentiate certain elements of the site, such as vessels or specific areas (for example, the Roman baths). This creates a controlled colour contrast that provides information without dominating the scene.

In areas with natural light through skylights, artificial lighting is regulated to accompany this presence, reducing its intensity and avoiding competition with daylight. On the other hand, in areas without natural light, artificial lighting takes on a more structuring role to ensure the continuity of the route and a homogeneous perception of the whole.

The museum also incorporates large exhibition shelves, which require lighting capable of showing both the whole and the detail: a uniform light that allows you to read all the pieces, combined with precise accents that facilitate the individual perception of each object, with a criterion similar to that of an exhibition room.

For perceptual and conservation reasons, the lighting levels are deliberately kept contained. This decision facilitates the progressive adaptation of vision as the visitor advances, avoids abrupt contrasts and respects the fragility of archaeological materials.

Sustainability and respect for heritage

The project demonstrates how lighting can enhance heritage from discretion: light accompanies history, interprets it and makes it legible for the contemporary visitor.

The renovation of the system has made it possible to significantly reduce energy consumption: it has gone from 75–100W luminaires (average approximately 80W) to powers of 2W, 3W and 12W, in a total of around 700 units. Today's technology becomes a silent ally that reinforces the museum's sustainability and contributes to preserving the cultural legacy in the long term.
