The use of visible concrete walls and structures is common in contemporary architecture, which is not surprising in representative interiors with raw concrete surfaces. This material significantly contributed to the architectural metamorphosis during the Modernist period. The use of concrete structures enabled the creation of innovative shapes and structures, aligning with Modernism's desire to experiment and reject traditional architectural forms. The shift in architects' approach from concealing to openly revealing building mate-rials, including concrete, contributed to the crystallisation of Brutalism, another important architectural style. Modern architectural ideas were reflected in museums and galleries built from the second half of the 20th century onwards, thus breaking the previous aesthetic standards for exhibition spaces. Concrete, originally a building's structural material, was introduced into exhibition halls and used as an interior finishing material and as a back-drop for exhibits. The analysis of selected examples allowed the description of three main stages in the change of approach to the use of concrete: from straightforward construction, through the treatment of concrete elements as noble details in the composition of exhibition interiors, to a unique form where the structural and textural possibilities of concrete allow it to incorporate elements of expression and narrative.
