Is Monaco building the world's most expensive apartment?

The principality of Monaco is the second-smallest independent state in the world and a haven for the world's rich and famous.

One building, the Tour Odeon, will be 170m (580ft) high and the second tallest building on the Mediterranean coastline. Its penthouse apartment will cover the top five floors and is rumoured to be on sale for about $400m (£250m) - making it the world's most expensive apartment.
