The Spanish ship Nuestra Señora de la Santísima Trinidad, was a Spanish first-rate ship of the line with 112 guns. This was increased in 1795–96 to 130 guns by closing in the spar deck between the quarterdeck and forecastle, and around 1802 to 140 guns, thus creating what was in effect a continuous fourth gundeck although the extra guns added were actually relatively small. She was the heaviest-armed ship in the world when rebuilt, and bore the most guns of any ship of the line outfitted in the Age of Sail.
