Sits the most expensive apartment in the world on the top of a skyscraper on the shores of the Principality of Monaco on the outskirts of the European continent, but the owner of this apartment is not yet known, which will be offered for sale next year, and is expected to be the share of one of the wealthy Gulf rich in luxury, elegance and excellence.

The apartment is scheduled to be offered for sale for $400 million, the British newspaper Daily Mail quoted the developer of the residential tower, which finally saw the light on the banks of Monaco, as a 560-foot high.

If the apartment is sold in the amount indicated, it will be the most expensive in the world at all compared to the apartments, and its price will be higher than the price of many luxury palaces, including the palaces of many heads of state in the world and the wealthy.
