Explore UN Headquarters. See what you can do when you visit the United Nations Headquarters. The United Nations was founded in 1945 after the Second World War by 51 countries committed to maintaining international peace and security, developing friendly relations among nations, and promoting social progress, better living standards and human rights.
With currently 193 Member States and two Permanent Observers – the flags of which fly along 1stAvenue in New York City – the United Nations is the only truly global Organization addressing challenges that cannot be tackled by one country alone. Working across the three inter-connected pillars of peace, development, and human rights, the United Nations system encompasses over thirty Agencies, Funds, Programmes and related entities.
The UN has evolved over the years to keep pace with a rapidly changing world. But one thing has stayed the same: it remains the one place on Earth where all the world’s nations can come together, discuss common problems, and find shared solutions that benefit all of humanity.
