High Quality Content by WIKIPEDIA articles! This is a list of Spanish battleships and monitors, covering the period from 1874 and the construction of the first modern vessels of these types during the Third Carlist War, through the 1940s when proposals were made for the construction of fast battleships and for the purchase of gun turrets from Germany for use in "large cruisers" - battlecruisers -, although only two monitor type vessels and four battleships were ever actually constructed for the Spanish Navy, while a pair of old armoured frigates were reconstructed into coast defense battleships.
