Despite the fact that huge buildings and massive structures don’t come at a cheap price, companies and governments across the world have continued to build them for hundreds of years.

Even with an expert team and a sound plan, it is still possible for building work to cost staggering sums of money. That is exactly what happened with these examples, which are the most expensive things ever built.
