Pirates of the Caribbean recently celebrated its 45th anniversary at Disneyland in California. Here be some things that you might not knowâ€¦ Pirates of the Caribbean was the last Disneyland attraction personally supervised by Walt Disney. The attraction was originally envisioned as a New Orleans-themed Blue Bayou Mart featuring a Pirate Wax Museum, housed in a 70-foot deep basement. The basement now serves as the grotto section of the attraction. The fire effects in the Burning Town scene were so realistic that prior to the attractionâ€™s grand opening, the Anaheim Fire Chief asked that the effects automatically shut off in the event of a real fire. It cost $15 million to build New Orleans Square ($8 million of which was spent on Pirates of the Caribbean). This is equal to the amount the United States paid for the real New Orleans as part of the Louisiana Purchase of 1803. The faÃ§ade of the attraction was partly inspired by the Cabildo building in Jackson Square in New Orleans, which served as the seat of the Spanish colonial government in 1799. It is also noted for being the site where the Louisiana Purchase was signed in 1803.
