The unity candle — two flames, one light.
Three candles on a table: one lit for each of you — often by your mums, your children, or whoever means the most — and a central candle you light together from your two flames. Your own candles stay lit, because you don't stop being yourselves when you marry. You just add a light you made together. It's simple, it's visual, and in the right room it's quietly devastating.
How it works
The two outer candles are usually lit early in the ceremony — a lovely job for mothers, grandparents or children, and a way to fold family right into the ritual. Then, after the vows or the ring exchange, you each take your candle and together light the central one. I say a few words about what the flames mean while you do it, and then the three candles burn on through the rest of the ceremony. Blended families often light it with more than two flames — at Sarah & Chris's castle wedding the handfasting did that job for a family of six, but a candle with a flame for each child works the same magic. When Laura & Chris married in the Kibble Palace, the glasshouse light made the flames almost invisible — which is why venue matters, and why I'll always tell you honestly whether yours will work.
Why couples choose it
Because it's the ritual that most visibly includes other people — the lighting of the family candles gives parents and children a real role, not a token one. Because the science of it appeals to the romantics and the engineers alike: two flames genuinely do become one. And because afterwards you have the candles themselves — many couples relight the central candle on anniversaries. It suits indoor venues, winter weddings and candlelit rooms best; if your heart is set on a clifftop or a beach, a quaich or an oathing stone will survive the weather far better than a naked flame.
Good to know
Check your venue allows open flames — a handful don't, and LED versions honestly don't carry the same weight. Use a hurricane vase or storm lantern for the central candle if there's any draught at all, choose pillar candles over tapers (they stand up by themselves and relight gracefully), and give the lighting roles to people at the rehearsal stage so nobody's surprised. For a winter ceremony, pair it with candlelight everywhere and it becomes the centrepiece of the whole room — my winter wedding guide has more on that.
