Fort San Fernando De Las Barrancas was a Spanish fort in what is nowMemphis, Tennessee. Established in May 1795, the fort was erected with a garrison of 150 men to defendSpanish claims of the territory at theFourth Chickasaw Bluff.[1][2] Although Spain renounced its claim to the area inPinckney's Treaty in 1795, it occupied the fort until either 1797 or 1798, when the Spanish dismantled the fort and established Fort Esperanza across the river near modernMarion, Arkansas.[3]
