The engineer Evaristo de Churruca says it is called a Basque custom by location, Bilbao therefore result from the union of the river and creek Euskera words: Bil-Ibaia-Similarly Bao.17, Tusell historian José Gómez argues that evolution is a beautiful addition vado.18, Iturrino writer Stephen Street said that the name derives from the two populations that existed on both sides of the river, rather than the river itself. The first, where it stands today would be called Old Town-Billa, in Euskara means 'battery', referring to the way they stack or heap.
The second, located on the grounds of the present neighborhood of Bilbao La Vieja and traditional ferrera, be called fog: vapor, exhalation.
