I suppose that, like many children, the Horse Chestnut was one of the first trees I learnt to recognise, obviously because its large round seeds were used for playing conkers but also through its panicles of cream and pink flowers, which we called "candles". I had always assumed that the word "conker" derived from "conqueror", since the object of the game is to conquer your opponent's specimen. However, I find that on old version of the game was played with snail shells and the alternative possibility is that "conker" is from the French word "conque" - a shell. We may never know the truth.
I have spoken of the seeds but not their protective spiny casing. Nor have I mentioned the distinctive leaves with their palmately compound arrangement of leaflets. In recent years the leaves have become disfigured by larvae of the Horse Chestnut Leaf Miner as shown in the picture. This moth, Cameraria ohridella, seems to have arrived in Britain in 2002 but has spread at an astonishing rate, affecting all the trees I've seen in the last two or three years.

The conkers are poisonous although cases but on the other hand I was told as a child that they could be used to make soap. This is true. The conkers contain saponins and these are the active ingredient in many soaps now available commercially although I have no plans to purchase them - or make the soap myself.
