European cathedrals: the transition to LED candles is underway

A movement that transcends borders

The transition from traditional candles to LEDs in places of worship is not an isolated phenomenon. Across Europe, major cathedrals and historic basilicas are making the switch. This movement, long discreet, has accelerated over the past decade, driven by three converging factors: safety, ecology and practicality.

An overview of the most notable initiatives across the continent.

Portugal: an unexpected pioneer

Lisbon Cathedral (Se de Lisboa)

The Se de Lisboa, a 12th-century Romanesque cathedral, was one of the first major European cathedrals to adopt LED candle holders on a large scale. After the earthquake of 1755 that had already ravaged the building, the question of risk prevention is particularly sensitive in Lisbon. LED candle holders were progressively installed in the side chapels, with a push-button donation system.

The result: the soot that blackened the Romanesque vaults has disappeared, and chapel maintenance costs dropped spectacularly.

Porto Cathedral (Se do Porto)

Porto followed Lisbon's example a few years later. The cathedral, welcoming over a million visitors per year, faced a considerable logistical challenge: hundreds of candles to manage daily, with the permanent risk of a tourist causing an incident. LEDs provided an elegant solution, allowing visitors to experience the votive gesture in complete safety.

Spain: Santiago de Compostela leads the way

The Cathedral of Santiago de Compostela, the endpoint of the famous pilgrimage route, welcomes millions of visitors each year. Managing votive candles represented a major logistical and safety challenge. With continuous flows of pilgrims, often tired and emotional after weeks of walking, the risk of an incident was permanent.

The progressive adoption of LED candle holders in several chapels has made it possible to:

• Reduce the staff needed to supervise prayer areas
• Eliminate flame-related incidents in a UNESCO-listed building
• Maintain devotional access without time restrictions
• Simplify donation management through electronic systems

Other Spanish cathedrals have followed suit: Seville, Barcelona (the Sagrada Familia uses mixed solutions) and several basilicas in Castile.

Italy: between tradition and pragmatism

Italy, with its unparalleled religious heritage, is a special case. The country has thousands of historic churches, and the votive candle is deeply rooted in popular culture. The transition is slower there but very real.

Several Roman basilicas have begun integrating LED solutions in their less-visited chapels, testing worshippers' reactions before wider deployment. In Veneto and Lombardy, entire dioceses have issued recommendations in favour of LEDs, particularly after candle-related incidents in poorly supervised rural churches.

The Vatican itself is closely monitoring these developments, aware that heritage preservation also means eliminating avoidable sources of risk.

France: a progressive adoption

In France, the transition is driven both by municipalities (owners of churches built before 1905) and by dioceses. The motivations are twofold:

• Safety of historic monuments: after the fire at Notre-Dame de Paris in 2019, the wake-up call was brutal. Although the fire was not caused by candles, it highlighted the vulnerability of religious buildings to fire.
• Reducing maintenance costs: in a context of constrained municipal budgets, traditional candle maintenance represents a significant expenditure.

Cathedrals such as Strasbourg, Chartres and Lyon have integrated LED solutions into some of their chapels. The town of Yvoire in Haute-Savoie was a pioneer in adopting a LumignonLED LED candle holder in its medieval church, proving that the technology is perfectly compatible with historic heritage.

Northern Europe: Scandinavian pragmatism

Nordic countries, often ahead on environmental matters, adopted LED candles in their places of worship earlier than the rest of Europe. In Sweden and Norway, many wooden churches — some dating from the Middle Ages — chose LEDs as an absolute precautionary measure. For wooden structures centuries old, the fire risk from candles was simply unacceptable.

In Denmark, the national Church issued official recommendations encouraging parishes to evaluate LED alternatives. The results are clear: no heritage loss from candles has been recorded in equipped parishes.

Eastern Europe: an emerging market

In Poland, Croatia and Slovenia, the transition is more recent but real. Major tourist basilicas (Czestochowa, Zagreb) are beginning to integrate LED solutions, often alongside traditional candles, in a gentle transition approach.

Switzerland: quality and innovation

Switzerland holds a special place in this European landscape. A country of precision and quality, it is both a user and producer of LED solutions for places of worship. LumignonLED, a Swiss manufacturer of LED candle holders, equips parishes in several cantons — Fribourg, Valais, Geneva — as well as in neighbouring France.

The trust-based push-button system, developed in Switzerland, addresses a universal European challenge: the decline of cash payment and the need to offer alternatives to vandalised coin mechanisms.

The drivers of an irreversible movement

Why is this transition accelerating across Europe? The reasons are structural:

• Stricter safety standards: insurers and heritage authorities are exerting growing pressure to reduce fire risks
• Unsustainable maintenance costs: with declining religious practice, parishes must optimise their resources
• Technological progress: today's LEDs faithfully reproduce the flame effect, making the transition aesthetically acceptable
• Environmental awareness: paraffin (petroleum-derived) and stearin in traditional candles raise ecological questions
• Payment evolution: coin systems are becoming obsolete in an increasingly cashless society

What next?

The trend is clear: within a decade, the majority of Europe's major cathedrals and basilicas will have adopted LED votive lighting solutions, in whole or in part. Local parishes will naturally follow, driven by the example of major buildings and the growing availability of quality products like those from LumignonLED.
