Following the success of our previous exhibitions Secret Communications 1, 2 and 3 — the last of which was in 2019 — Crypto Museum and the Foundation for German Communication have once again teamed up and are pleased to announce Secret Communications 4 — to be held in Duivendrecht (Netherlands). Please note that for the first time, there are two weekends in which we will be open on two successive days.
