One of the remarkable phases of Modern Architecture is ‘Minimalism’. This movement concerns with stripping away the unwanted details and defines the true essence of any given architectural element. It prevailed among architects who purposed simplicity, transparency, and spirituality. Its spaces interact with nature which makes users enter an atmosphere of reverence, asceticism, and silence. The problem is; 'Minimalist' approach witnessed a clear progress in art, décor, and interior design but got quite disappeared in architecture; just few architects who still design projects depending on it. This paper, therefore, aims to read and interpret the language of 'Minimalism' in architecture, understanding which design elements should be used to give a space the character of being 'minimal'. To achieve this aim, the paper tries to uncover the philosophy of 'Minimalism', its origins, and extracts its design criteria. After that, the paper analyzes works of Tadao Ando, Luis Barragán, and Alberto Campo Baeza, as case studies, to understand their architectural languages and how these works became successful landmarks. One of the important key findings is: In 'Minimalism', nature became architecturalized through clear spaces and simple geometries. It creates a strong dialogue between elements of architecture and elements of nature.
