🕯️ The Origins of Halloween — From Samhain to Jack-o’-Lanterns
Every year on October 31st, homes around the world glow with carved pumpkins and flickering candles.
But behind the costumes and candy lies a story that began over 2,000 years ago.
Halloween traces its roots to the Celtic festival of Samhain — a time when people believed that the veil between the living and the dead grew thin.
Later, with the spread of Christianity, the evening before All Saints’ Day became known as All Hallows’ Eve — or Halloween.
Traditions evolved, and symbols like pumpkins, black cats, and scarecrows turned into what we now love as the spooky season.
Today, Halloween has become a joyful mix of creativity, storytelling, and community spirit — and now, thanks to LEGO® bricks, you can bring that magic into your home in a fun and decorative way.
🧱 Free LEGO® Halloween Mosaic Build Plans
At BrickMosaicDesigner.com, we love turning creative ideas into colorful brick mosaics. This Halloween, we’re sharing three brand-new, free LEGO® brick mosaic build plans inspired by classic Halloween symbols.
Each design comes with easy-to-follow instructions and can be built using standard LEGO® bricks you already have.
🎃 Jack-o’-Lantern Mosaic (100×100 studs)
Nothing says “Halloween” like the glow of a Jack-o’-Lantern.
This 100×100 studs / 80×80 cm/ 31.5×31.5 inch LEGO mosaic recreates the warm orange light and carved grin of the world’s most famous pumpkin.
The legend of the Jack-o’-Lantern comes from Irish folklore — the story of Stingy Jack, who tricked the Devil and was cursed to roam the Earth with only a glowing coal inside a hollowed turnip.
When Irish immigrants arrived in America, they found pumpkins easier to carve — and the rest is history.

This 150×150 studs LEGO® mosaic brings that eerie countryside magic to life with rich autumn tones and striking brick patterns. Built from genuine LEGO® bricks, this design is a true original, crafted exclusively for Halloween 2025 as part of the ArtForBricks seasonal collection — a mosaic that combines rustic beauty with festive imagination.

🐈 Black Cat Relief Mosaic (100×100 studs)
Mysterious, elegant, and just a little bit magical — the black cat is one of Halloween’s most iconic symbols.
In folklore, black cats were believed to bring luck (or misfortune!) and often appeared as witches’ companions.
This 100×100 studs relief mosaic adds a new creative dimension — quite literally.
Its 3D texture creates beautiful light and shadow effects that make the design come alive, especially when placed under soft lighting.

✨ Tip: Position it near a candle or LED light — the raised structure gives your Halloween display a haunting glow.
