"Competition project for the art, ethnographic and history museum in Katowice is presented. The original Silesian Museum (1936-39) had been an advanced modernistic building destroyed by the Nazis because of its Polish contents and International Style architecture. After 50 years the competition was to choose an equally high quality design. A series of patterns was introduced: 1) concerning the museum as institution: - on the hand as "temple of arts", -on the other hand as: "Disneyland"; 2) concerning the specific Silesian character: - typical of the region "small town structure" with its "market square" and "town hail", - "witness of the past" being a building from the 1950s, - coal mining tradition symbolized by "hole in the Earth" and tectonic "crack"."
