TEHRAN -- The lockers in Tokyo’s subway are currently containing carvings of Iranian earth artist Ahmad Nadalian, the Persian service of Cultural Heritage News (CHN) agency reported here on Sunday.

A brainchild by Tokyo-based Belgian artist Eric Van Hove, the initiative has been entitled “Treasure”.

Only people who have the code of the lockers can gain access to the works.

Van Hove locks the chests and sends the codes to different people, enticing them to come and see the works, Nadalian said.

In the second stage, visitors are allowed to take the stone carvings and bury them in nature and record the information of the place on their cell phones’ GPS system.

During his relationship with Japanese artists, Nadalian found out that cell phone plays a very important role in Japan.

“Japanese make use of all systems which are defined in a mobile phone while most of them have been left unused in Iran.”

Nadalian previously organized a program entitled “Hidden Treasure: An Exhibition for the Next Millenniums” two years ago in the Polur area of Mount Damavand, 40 kilometers northeast of Tehran.

During the plan, he buried his works to save them for next generations.
