The Eighth Army Band's melody plays in tribute to the veterans who took part in the Korean War.
On October 24th, 1945, the United Nations was established to ensure the common prosperity of the international community, and when the Korean War broke out in 1950, it played a key role in bringing peace to the peninsula.
"Not long after the UN's creation, it activated the collective security system for the first time and intervened in the Korean War in support of South Korea, which eventually led it to contribute to the international community as a middle power country."
To thank the UN and war veterans from around the world, the memorial has come up with the very first "UN Culture Week" which runs until October 24th.
It features a wide range of events including exhibitions showing the timeline of the Korean War along with introductions of countries that sent troops.
"Among the participants in the war was Colombia the only member state in South America to officially dispatch troops to the Korean Peninsula. In commemoration of the 70th anniversary of the Colombia's participation, a special exhibition was prepared."
There are also special talk sessions with ambassadors.
As one of the nations of the Neutral Nations Supervisory Commission, the Polish ambassador was the first to hold a talk.
Sharing the tragic story of Korean orphans who were brought up in Poland, he stressed how it is important to know the past to avoid a repeat of the tragedy.
"If you find the remedy how to prevent wars, I would congratulate you whole-heartedly. No one can find it. It depends on the will of the people and to find, to compromise and consensus not to refer to the argument of power but rather to find the power of argument. This is a big difference."
Experts invited to discuss the issue of keeping peace on peninsula say it is important to remember that inter-Korean relations are a global issue.
"I think our Korean government should remember that we are not only focusing on North Korean issue related to national issues but also international issue where we need a global cooperation to solve the problem."
Sharing gratitude and paying tribute to those from around the world who died during the Korean War, the events share hope for a peaceful future.
