Castillo San Cristóbal (San Juan) Informations

Castillo San Cristóbal, is a fortress in San Juan, Puerto Rico. It was built by Spain to protect against land based attacks on the city of San Juan. It is part of San Juan National Historic Site.

Castillo San Cristóbal is the largest fortification built by the Spanish in the New World. When it was finished in 1783, it covered about 27 acres of land and basically wrapped around the city of San Juan. Entry to the city was sealed by San Cristóbal's double gates. After close to one hundred years of relative peace in the area, part of the fortification (about a third) was demolished in 1897 to help ease the flow of traffic in and out of the walled city.

This fortress was built on a hill originally known as the Cerro de la Horca or the Cerro del Quemadero, which was changed to Cerro de San Cristóbal in celebration of the Spanish victories ejecting English and Dutch interlopers from the island of this name in the Lesser Antilles, then forming part of the insular territorial glacis of Puerto Rico.

Castillo de San Cristóbal also contains five cisterns that were used for the storage of water during the ages of the Spanish Colony. They are extremely large (24 ft tall, 17 ft wide and 57 ft long) and were used as bomb shelters during World War II. They could be used for a future war again with some refurbishments.

1521 – San Juan founded by Spanish settlers from Caparra.

1539 – Construction of the first fortified defenses at Castillo San Felipe del Morro and La Fortaleza, with batteries aimed at the harbor entrance.

1595 – The English attack San Juan, led by Sir Francis Drake, 25 ships penetrated the line of fire from El Morro. At the end of the battle the English fled taking some prisoners but no treasure, the reason for which they attacked.

1598 – The English attack San Juan a second time, this time led by George Clifford who wanted to clean England's honor which had been "dirtied" by Sir Francis Drake's defeat, he organized the greatest squadron ever put together by the English against Spain. The first battle resulted in a Spanish victory, but the exhausted Spanish troops couldn't impede the English entry into San Juan. On 18 June Cumberland with his forces advanced and then swept into San Juan's streets meeting little resistance; he found that some of the citizenry had already fled. The government officials and other residents had taken refuge in El Morro and 250 Spanish soldiers are ensconced within the Morro Citadel. Soon after the town had been occupied, the English had artillery ferried ashore from their fleet and a formal siege was instituted. Two days later the siege was under way and El Morro was bombarded from both land and sea while in the meantime Cumberland set about sacking the town. Knowing that the Spanish were short of supplies, the English preferred to lay siege to the castle of El Morro rather than destroy it. After nearly 15 days huddled inside El Morro, short of food and ammunition and being constantly bombarded, the Spanish governor Antonio Mosquera requested terms on 30 June for a surrender. Cumberland refused this request and set his own terms for the Spanish surrender of which Mosquera eventually agreed to. He and his followers were repatriated to Cartagena several weeks later.

The victory had cost Cumberland nearly 60 casualties; however, as the same dysentery that had crippled much of the Spanish it had then spread to Cumberland's men, incapacitating nearly 600 - 700 of them as well as which included forty accidents. With barely enough troops to crew his ships, much less maintain control of the prize he had seized from Spain, Cumberland finally decided to leave the island. Before he left however he ordered the sacking of San Juan and then ordered the destruction of the crops. His troops stole the organ and bells from the cathedral and took booty ranging from 2,000 slaves to a marble windowsill that caught his eye. Cumberland sailed for England with some ships on 14 August, then on 23 September Berkeley followed with his main body along with around 70 artillery pieces from the fort. Clifford on his return to England was proclaimed as a hero of sorts and as a consequence with his limited booty was well rewarded for his efforts including a patent from the Queen.

1625 – The Dutch attack and take San Juan from the land side. Construction of some form of defense for San Cristóbal Hill ordered to prevent other attacks from the land side.

1634 – A small triangular redoubt is built on the high ground known as San Cristóbal on the northeast side of San Juan.

1766–1783 - Main period of construction of San Cristóbal as we see it today under the directions of Royal Engineers Tomás O’Daly and Juan Francisco Mestre.:61–65

1787 – An earthquake damages the structure of both San Felipe del Morro and San Cristóbal.

1797 – San Cristóbal helps repel the attack on San Juan from the land side by a British invasion force of 7,000 - 13,000 men commanded by Sir Ralph Abercromby. Abercromby's forces, one of the largest ever to invade Spanish territories in America, are halted a mile from San Cristóbal at the Escambrón defenses, also known as San Juan's First Line of Defense; see Fortín de San Gerónimo.

1824 – María de las Mercedes Barbudo, a political activist who was the first female from Puerto Rico "Independentista", meaning that she was the first Puerto Rican woman to become an avid advocate of Puerto Rican Independence, and who joined forces with the Venezuelan government, under the leadership of Simon Bolivar, to lead an insurrection against the Spanish colonial forces in Puerto Rico., was held captive in the fort pending her exile to Cuba.

1855 – Mutiny by the San Cristóbal artillery brigade against the Spanish crown. The Castillo is held by rebels for 24 hours causing panic in the city when the cannons are turned around and aimed at the city.

1897 – A large segment of 18th century walls are dynamited from San Cristóbal to the harbor docks to allow San Juan to expand.

1898 – On 10 May 1898, the first shot which marked Puerto Rico's entry into the Spanish–American War was ordered by Captain Ángel Rivero Méndez is against the USS Yale from Castillo San Cristóbal's cannon batteries. San Cristóbal's gunners duel with US Navy warships during a day-long bombardment 10 May 1898. Six months later Puerto Rico becomes US territory by terms of the Treaty of Paris which ends the Spanish–American War.

1942 – Still an active military base when the United States entered World War II, concrete pillboxes and an underground bunker control center are added to the ancient defenses of the Castillo San Cristóbal. Cisterns were to be used as fallout shelters.

1949 – San Juan National Historic Site is established as the most impressive structure in the new world.
