Fort Frontenac was a French trading post and military fort built in 1673 in Kingston, Ontario, Canada. It was positioned at the mouth of the Cataraqui River where the St. Lawrence River leaves Lake Ontario (at what is now the western end of the La Salle Causeway), in a location traditionally known as Cataraqui. The original fort, a crude, wooden palisade structure, was called Fort Cataraqui but was later named for Louis de Buade de Frontenac, Governor of New France (Count Frontenac), who was responsible for building the fort. The fort, however, was still often referred to as Fort Cataraqui.
The intent of Fort Frontenac was to control the lucrative fur trade in the Great Lakes Basin to the west and the Canadian Shield to the north. It was one of many French outposts that would be established throughout the Great Lakes and upper Mississippi regions. The fort was meant to be a bulwark against the English who were competing with the French for control of the fur trade. Another function of the fort was the provision of supplies and reinforcements to other French installations on the Great Lakes and in the Ohio Valley to the south. Frontenac hoped that the fort would also help fulfill his own business aspirations.
The fort was built beside a small sheltered bay that the French could use as a harbour for large lake-going boats. Unlike the Ottawa River fur trade route into the interior, which was only accessible by canoes, larger vessels could easily navigate the lower lakes. The cost of transporting goods such as furs, trade items, and supplies through at least the lower Great Lakes would be reduced. The fort would protect this harbour.
René-Robert Cavelier, Sieur de La Salle, the original administrator and commander of the fort, built many additional buildings and even brought in domestic animals with the hope of inducing settlers to come to the Cataraqui outpost. He began replacing the wooden fort with a more secure stone fort in 1675. A description of the fort written in the 17th century mentions that:
"Three quarters of it are of masonry or hardstone, the wall is three feet thick and twelve high. There is one place where it is only four feet, not being completed. The remainder is closed in with stakes. There is inside a house of squared logs, a hundred feet long. There is also a blacksmith's shop a guardhouse, a house for the officers, a well, and a cow-house. The ditches are fifteen feet wide. There is a good amount of land cleared and sown around about, in which a hundred paces away or almost there is a barn for storing the harvest. There are quite near the fort several French houses, an Iroquois village, a convent and a Recollet church."
La Salle used Fort Frontenac as a convenient base for his explorations into the interior of North America.
Fur trade rivalries resulted in the Iroquois Wars. The French and Iroquois were never on very friendly terms. A peace treaty was signed in 1667, but the war was renewed in the 1680s, and this renewal of war affected Fort Frontenac. In 1687 the Marquis de Denonville began a campaign against the Iroquois and gathered an army to travel into the Seneca territory south of Lake Ontario. To quell suspicion about his motives, Denonville said he was merely travelling to a peace council at Fort Frontenac. As Denonville and his army moved up the St. Lawrence toward the fort, several Iroquois, including women and children, many of whom were friendly to the French, were captured and imprisoned at Fort Frontenac by intendant de Champigny ostensibly to prevent them from revealing Denonville's troops' location. Some were sent to France to be used as galley slaves. Denonville's troops and native allies went on to attack the Seneca.
In retaliation for these incidents the Iroquois attacked a number of French settlements, including Fort Frontenac. The fort and the settlement at Cataraqui were besieged for two months in 1688. Although the fort was not destroyed, the settlement was devastated and many defenders died, mostly from scurvy. The French abandoned and destroyed the fort in 1689, claiming that its remoteness prevented proper defense and that it could not be adequately supplied. The French again took possession of the fort in 1695 and it was rebuilt.
Increased tension between the British and the French in the 1740s led to the French upgrading the fort's defensive capabilities by adding new guns, building new barracks and increasing the size of the garrison. Despite these improvements the fort's strategic significance gradually decreased. Other forts such as Fort Niagara, Fort Detroit, and Fort Michilimackinac became more important. By the 1750s Fort Frontenac essentially served only as a supply storage depot and harbour for French naval vessels, and its garrison had dwindled.
During the Seven Years' War between Britain and France, who were vying for control of the North American continent, the British considered Fort Frontenac to be a strategic threat since it was in a position to command transportation and communications to other French fortifications and outposts along the St. Lawrence - Great Lakes water route and in the Ohio Valley. Although not as important as it once was, the fort was still a base from which the western outposts were supplied. The British reasoned that if they were to disable the fort, supplies would be cut off and the outposts would no longer be able to defend themselves. The Indian trade in the upper country (the Pays d'en Haut) would also be disrupted. Control of the French supply route was not the only reason for attacking the fort, however. Fort Frontenac was also regarded as a threat to Fort Oswego, which was built by the British across the lake from Fort Frontenac in 1722 to compete with Fort Frontenac for the Indian trade, and later enhanced as a military establishment. Indeed, General Montcalm used the Fort as a staging point to attack the fortifications at Oswego in August 1756. The British also hoped that taking the well-known fort would boost troop morale and honour after their demoralizing battle defeat at Fort Ticonderoga (Fort Carillon) in July 1758. And so, in August 1758, the British under the command of Lieutenant-Colonel John Bradstreet left Fort Oswego with a force of a little over 3000 men and attacked Fort Frontenac. The fort's garrison of 110 men, commanded by Pierre-Jacques Payen de Noyan et de Chavoy, surrendered and were allowed to leave. Bradstreet captured the fort's supplies and nine French naval vessels, and destroyed much of the fort. He quickly departed to avoid further conflict with any French support troops.
For the British, Fort Oswego was secured, and the army's reputation was restored. For the French, the fort's loss was considered to be only a temporary setback.'Fort Frontenac's surrender did not succeed in completely severing French communications and transportation to the west since other routes were available (e.g. the Ottawa River - Lake Huron route). Supplies could be moved west from other French posts (e.g. Fort de La Présentation). In the long term, however, the surrender compromised French prestige among the Indians, which was a major factor leading to the defeat of New France in North America. Since the fort was no longer perceived to be important to the French, it was never rebuilt and was left abandoned for the next 25 years.
French imperial power was waning in the late 1750s, and by 1763 France had withdrawn from the North American mainland. Cataraqui and the remains of Fort Frontenac were relinquished to the British.

United Empire Loyalists who had fled the United States after the American War of Independence formed a community in the vicinity of the fort and along the Cataraqui River waterfront. To protect the growing population of Cataraqui (eventually to be called Kingston) from attack from the United States, the British partly rebuilt Fort Frontenac in 1783 to accommodate a military garrison. By October 1783, a lime kiln, hospital, barracks, officers' quarters, storehouses, and a bakehouse were completed on the site of the old fort. In 1787, the rebuilt fort became known as Tête-de-Pont Barracks. Many of the present barrack buildings were built between 1821 and 1824. During the War of 1812, the fort was the focus of military activity in Kingston, having housed many military troops.
After British troops were withdrawn from all Canadian locations except Halifax in 1870-71, the militia authorized the creation of two batteries of garrison artillery which provided garrison duties and schools of gunnery. "A " Battery School of Gunnery was established at Tête-de-Pont Barracks and other locations in Kingston ("B " Battery was located in Quebec). These batteries were known as the Regiment of Canadian Artillery. When this regiment evolved into the Royal Canadian Horse Artillery (RCHA), it's headquarters was based at the Tête-de-Pont Barracks from 1905 to 1939. After the RCHA left for operational duties during the Second World War, the fort was used as a personnel depot. In 1939 the site of the fort again became known as Fort Frontenac. Canadian Army staff training began at Fort Frontenac when the Canadian Army Staff College moved to the fort from the Royal Military College in 1948. The college is now known as the Canadian Land Force Command and Staff College. Fort Frontenac was also the location of the National Defence College until 1994.
The fort has undergone extensive archaeological investigation and partially reconstructed remains of the northwest bastion and curtain wall can be seen.
Fort Frontenac was designated a National Historic Site in 1923.
