Shipyard
A shipyard (also called a dockyard) is a place where ships are built and repaired. These can be yachts, military vessels, cruise liners or other cargo or passenger ships. Dockyards are sometimes more associated with maintenance and basing activities than shipyards, which are sometimes associated more with initial construction. The terms are routinely used interchangeably, in part because the evolution of dockyards and shipyards has often caused them to change or merge roles.

Besides as a shipyard, the Crown used the Shipyard for other functions since its first centuries of operation. Because of their large size, they served to host assemblies and public celebrations. They were also a natural place to store the booty and the prisoners captured by the fleets of the Castilian kings. Sometimes they served as jails for the social elite, for example for the nobles related to the king Peter of Castile after the victory of his rival Henry II of Castile.
