The history of architecture is marked by a rich array of styles and expressions, each of which reflects the specific environment it was created in. Numerous unique narratives have emerged, giving rise to various architectural traditions. The notion of a single, universal tradition is quickly debunked when one explores the pages of any architectural history book.
While contemporary architectural movements may share common principles, it's important to note that this doesn't necessarily result in a uniform appearance. However, when we consider the diversity of historical architectural styles and traditions, it becomes evident that specific regions have distinct architectural identities. Portugal has a well-defined architecture, and Carlos Castanheira is one of its notable representatives.
