From the Wikipedia page for Arch of Reunification:

The Arch of Reunification is a sculptural arch located in Pyongyang, the capital of North Korea. It was constructed in 2001 to commemorate Korean reunification proposals put forward by Kim Il-sung.

The concrete arch straddles the multi-laned Reunification Highway leading from Pyongyang to the DMZ. It consists of two Korean women in traditional dress (chos?n-ot) symbolizing the North and South – leaning forward to jointly uphold a sphere bearing a map of a reunified Korea.

The plinth of the structure is engraved with messages of support for re-unification and peace from various individuals, organizations and nations.
