Silesia has a multiplicity of faces. Besides the name, it is difficult to find a common denominator between Lower and Upper Silesia or Cieszyn and Opole Silesia.
Silesia is mainly openness. Silesia owes its strong presence in the history of the European civilisation to this feature. Called the “emerald of Europe” in the 17th century, in the 19th‑century it became one of the main centres of the industrial revolution. The gene of modernity sprouted in this period and is growing fruit now.
