The Secret Telephone Exchange

Above a bakery in Amersfoort, young women supported the resistance through a secret telephone exchange.

During the Second World War, Vonk confectionery on the Langestraat appeared to be just an ordinary bakery in the centre of Amersfoort. Customers came in for bread and pastries, while above the shop, important resistance work was taking place in secret.

In 1944, the CID set up an illegal telephone exchange here. CID stands for Centrale Inlichtingendienst — a resistance organisation that gathered secret intelligence during the war and relayed messages without the Germans being able to intercept them. From the telephone exchange, resistance groups in Amersfoort and other towns kept in contact with one another.

The resistance's telephone exchange

A remarkable object from the collection recalls this history: the original telephone exchange itself. Using the device, telephone operators connected calls between resistance members in Amersfoort and other parts of the Netherlands. Later, the advancing Canadian troops also used the secret lines.

Dangerous

The work was dangerous. During a raid, the women had to make the exchange disappear at lightning speed. Within seconds, they could hide the device in the ceiling above their workstation. This allowed the Amersfoort resistance to remain active longer and ensured that important messages could be passed on safely.

The convent

The young women who worked at the telephone exchange were not allowed to leave the building during their shifts. To avoid discovery, they remained inside for long periods. As a result, the hiding place quickly earned the nickname 'het Klooster' — the Convent.

The telephone exchange shows how ordinary city locations took on an extraordinary role during the war. Behind the smell of fresh bread lay a world of tension, secrecy and cooperation. The story of the Convent is a reminder of the courage of Amersfoort residents who, often invisibly, fought for their city's freedom.
