The Hague International Open Day

OPCW Headquarters, The Hague, the Netherlands

22 September 2019

Once a year the OPCW opens its doors to the public for The Hague International Open Day.

Join us on 22 September from 11:00 to 17:00 to learn out about chemical weapons and what is being done to permanently eliminate them.

Take part in our new interactive demo on how OPCW inspectors work in the field, try on the same gear that our inspectors wear, attend expert presentations, and take a photo with the OPCW’s Nobel Peace Prize. 

Other activities include presentations on how to become an OPCW intern, and an art session for our youngest visitors.
