Where is the Witness convention held in Nederlands?

Jehovah's Witnesses do not hold conventions or large gatherings in the Netherlands. Instead, they usually organize smaller assemblies and meetings on a local or regional level, known as "circuits" or "districts," to gather and worship together. Jehovah's Witnesses in the Netherlands, or any country, follow the guidelines and arrangements provided by the central branch office of the organization to conduct their spiritual activities and gatherings.
