Taumatawhakatangihangakoauauotamateapokaiwhenuakitanatahu
What is it? The longest name for a place in the whole world! 89 letters!
The board above the name explains that Tamatea was a chief, a warrior and an explorer. One day, he met with his people a rival tribe, and during the battle his brother was killed. He was so grieved that he stayed some time at that very place, and each morning he sat on the hill and played a lament for his lost brother.
So the name of the place really means: the summit where Tamatea, the man with the big knees, the climber of mountains, the land-swallower who travelled about, played his nose flute to his loved one.
