Yes, it is difficult. I remember the story a few years ago, from Turkey.

Artifacts discovered during construction work Marmaray, Istanbul, Turkey. Artifacts are now stored in two museums, namely in Yenikapi near Marmaray station, another in Darphane.

Marmaray is an electric subway that divides the Bosphorus,

The project, which began in 2004, was suspended for several years due to the discovery of ancient artifacts during the excavation of the tunnel.

It is said that this archaeological object is a relic of Byzantium 8,500 to 2,500 years ago. After all the artifacts are removed and printed correctly, construction continues.

Marmaray is a Turkish dream since 1876 in the time of Sultan Abdul Mecit II. More than 150 years ago, the Ottoman Sultan dreamed that there would be an underwater submarine in the Bhosporus Strait connecting Asia and Africa.

His successor, Sultan Hamid who ruled from 1922 to 1924 then made his sketches. But until the end of the empire this idea did not materialize. At the time of Prime Minister Erdogan, the expensive sea lanes were realized.

Subway line 13.6 kilometers long, capable of carrying 75,000 people per hour or 1.5 million people per day. Handles about 20 percent of car traffic in Istanbul with a population of 15 million people.
