The Burj Al Arab, often referred to as the “sail” hotel due to its unique sail-like shape, seems almost otherworldly in its design. Its construction was a significant engineering and architectural achievement, pushing the boundaries of what was thought possible in building design and construction.

While the Burj Al Arab is one of the most iconic and expensive hotels ever built, it is not the most expensive hotel construction project in history. Several other hotel projects have surpassed it in terms of construction costs. Here are some of the most expensive hotel construction projects:
