Why Amsterdam Has 3 X: The Story Behind the City's Iconic Symbol

Whether you’re strolling through the bustling streets of Amsterdam, catching a glimpse of a city flag, or browsing a souvenir shop, you’ve likely come across the mysterious three Xs — often shown as XXX . But what do they mean, and why does Amsterdam have 3 Xs in the first place?

It’s one of the most asked questions by tourists and even some locals. These three Xs, known officially as St. Andrew’s Crosses, are more than just cool graphics — they carry historical, cultural, and symbolic weight that goes back centuries. Let’s dive into the history and meaning of Amsterdam’s iconic triple X emblem.

The Origin of the 3 Xs: St. Andrew's Crosses

The three Xs are actually three Saint Andrew’s Crosses . Saint Andrew was a Christian martyr who was believed to have been crucified on an X-shaped cross in the 1st century AD. His cross became a symbol of protection and resilience in heraldry — the system of coats of arms used in medieval Europe.

In Amsterdam’s case, the city’s coat of arms features a black shield with three vertical white Saint Andrew’s Crosses, bordered by red. The design dates back to the early 1500s , and has been officially used since at least 1505.
