Replica of Nuestra Señora de la Santísima Trinidad
The original ship, built in Havana Cuba and designed by an Irish naval architect, Matthew Mullen, was launched in 1769 as an 112-gun three-decker  (some sources say 116 or even 120 guns). She was considerably larger than her British contemporary Victory and somewhat bigger than the French Bretagne.
In 1797, she was the flagship of Teniente General José de Córdoba, the Spanish commander, at Battle of Cape St Vincent on 14 February 1797, where she was badly damaged and nearly captured by the British fleet. She was first in action with the British ship Captain (74), commanded by Commodore Nelson, and Culloden (74). She was then attacked by the Blenheim (90),Orion (74), Irresistible (74) and Excellent (74). By now she was severely damaged, having lost all her masts and with half of her crew killed or wounded. She struck her colours, but the British failed to take possession and she was saved by the Pelayo (74) and Principe de Asturias (112). Several days later, Santísima Trinidad was spotted, still damaged, making her way back to Spain, and engaged by the 32-gun frigate HMS Terpsichore under Captain Richard Bowen, but she escaped. She eventually returned to Cadiz for repairs.
Eight years later, commanded by Francisco Javier Uriarte and Rear Admiral Baltasar Hidalgo de Cisneros, she took part in the Battle of Trafalgar on October 21, 1805, as part of the combined Franco-Spanish fleet. Due to her great bulk, her helm was unresponsive in the light winds of the day, contributing to her ineffective service of the combined fleet’s cause. Her great size and position immediately ahead of the fleet flagship Bucentaure made her a target for the British fleet, and she came under concentrated attack by several ships. She lost her mast and eventually surrendered to the Neptune, commanded by Captain Thomas Fremantle. She was taken in tow by the Prince, but sank in a storm the day after the battle having been scuttled by her British captors. Credit: wikipaedia
