On the 7th of December Colombia celebrates the Little Candles Night. It is celebrated on the eve of the Immaculate Conception, (the 8th of December) which is a holiday in Colombia. It is also the unofficial beginning of Christmas in Colombia. (The truth is that the very unofficial date in just after Halloween, when Christmas decorations appear all over the city 😉 )
On this day people place candles on the streets, in front of the buildings and parks.
