When Were Lights Put in Castles?

 

Introduction

Ever walked through a medieval castle and wondered—how did people even see in here? Before the flip of a light switch existed, castles relied on primitive yet clever methods to light up their massive halls. Let’s take a bright stroll through history and uncover when lights were first introduced in castles and how that evolved over centuries.






🔥 Early Lighting Methods in Castles

Torches and Firelight

In the early days, torches were the go-to. Made from wooden sticks wrapped in cloth and soaked in pitch or resin, torches offered limited but immediate light. They were smoky, dangerous, and messy—but did the job.

Tallow Candles and Beeswax Candles

Candles were a more refined option. Tallow candles, made from animal fat, were cheap but smelly. The rich, however, preferred beeswax candles for their cleaner burn and pleasant aroma.

Oil Lamps: Olive, Fish, and Whale Oils

Oil lamps came next. Using terracotta or metal containers, these lamps were fueled by oils—mainly olive oil in Europe. In coastal areas, fish oil or whale oil served as alternatives.


⚠️ Challenges of Lighting Medieval Castles

Fire Hazards and Smoke Damage

Lighting involved fire—literally. Open flames in wooden structures were a recipe for disaster. One spark could burn an entire hall.

Limited Reach of Light in Large Halls

Castles were massive. A single candle or torch barely lit a corner. Shadows dominated, and many rooms were dim even during the day.

Cost and Labor Involved

Maintaining hundreds of candles wasn’t cheap. It needed a full-time staff for lighting, extinguishing, and cleaning soot stains from walls and ceilings.


🏰 Architectural Design and Light Management

Use of Arrow Slits and Windows

Designers cleverly used narrow windows (arrow slits) to let in light during the day while still keeping defenses strong.

Placement of Chandeliers and Wall Sconces

Chandeliers with multiple candles were hung in great halls, often lowered by chains for lighting. Wall sconces helped spread light more evenly.


🔮 Transition Period — Pre-Modern Lighting

Introduction of Lanterns with Glass

By the 1600s, lanterns with glass panels became common, reducing fire risk and spreading light better.

The Use of Mirrors and Reflective Surfaces

Some castles even used polished metal or mirrors to reflect candlelight, brightening up rooms more efficiently.


💡 When Were Lights Electrically Put in Castles?

Early Experiments with Gas Lighting (1800s)

Before electricity, some castles experimented with gas lighting—especially in the 19th century. Gas pipes and jets allowed safer, consistent light.

Castles Converted to Electricity (Late 19th – Early 20th Century)

Electricity entered royal residences around the 1880s–1900s. Windsor Castle, for example, got electric lighting in 1883—one of the first historical buildings to make the switch.

Famous Examples

  • Windsor Castle – Electric lighting in 1883

  • Neuschwanstein Castle (Germany) – Designed with electric lighting in 1886

  • Edinburgh Castle – Gradual conversion in early 20th century





🛠️ Modern-Day Restoration and Lighting in Castles

Preserving Historical Aesthetics

Modern restorers carefully hide electric wires behind walls or beams, maintaining that “medieval vibe” while using modern tech.

Smart Lighting and Museum Adaptations

Some castles now use LED lighting with dimmable and color-shifting features to preserve artifacts and offer immersive experiences for visitors.


🔌 Secondary Lighting Systems in Royal Residences

Hidden Wiring and Low-Impact Fixtures

Royal residences incorporate hidden lighting systems to reduce visual impact on historic decor.

Safety Regulations in Historical Buildings

Modern fire safety codes mean castles can’t just rely on candles anymore. Most now use certified low-voltage systems.


📊 Comparing Lighting Through the Ages

From Flame to Filament

Lighting went from flame (torches, candles) → gas → electricity → LEDs.

Energy Efficiency in Castle Lighting Today

With solar panels and LED tech, some castles now operate sustainably without losing historical charm.


🌍 Cultural Significance of Castle Lighting

Symbol of Wealth and Power

Only the rich could afford constant lighting. The more beeswax candles you burned, the wealthier you appeared.

Light as a Defensive Element

Light played a defensive role—illuminating outer walls to spot attackers at night.


🎬 Castle Lighting in Popular Culture

Movies, TV Shows, and Video Games

Think of “Game of Thrones” or “Harry Potter”—lighting sets the tone. Filmmakers use a mix of firelight and CGI to create authentic medieval feels.


📅 Lighting Technology Timeline for Castles

900s–1300s – Torches and candles
1400s–1600s – Oil lamps, basic lanterns
1800s – Gas lighting
1880s–1900s – Electric lights
Modern Era – LEDs, smart lighting


💡 Interesting Facts About Castle Lighting

  • A single medieval chandelier could hold 30+ candles.

  • Some castles used fish bladders instead of glass in windows.

  • Electric lighting was seen as “magical” when first introduced.


📝 Conclusion

So, when were lights put in castles? Well, they’ve always had light—just not like we know it. From flickering torches to smart LED lighting, the journey of illumination in castles mirrors human innovation. It’s a glowing testament to how we’ve tamed darkness across centuries.
