What is "euskalduna"

Euskalduna de Construcción y Reparación de Buques de Bilbao (shortened to Euskalduna) was an engineering company specialising in ship construction, later rail and road vehicles. The company was based in Bilbao, Spain and operated from 1900 until closure in 1984.

The site of the yard is now used for the Euskalduna Conference Centre and Concert Hall, as well as the Ria de Bilbao Maritime Museum (Bilbao Maritime Museum).
