Many of these gray giants were built between 1950 und 1970s. This type of architecture is known as Brutalism and was mostly popular in post-war Europe, India, and the Eastern Bloc. Today, many of these buildings are demolished and lie in ruins. However, many are empty and exist as monuments to a bygone era. The monuments constructed in this style are especially interesting in ex-Yugoslavia countries. Brutalism was typically represented in buildings without paint or dressings. In many, they evoke silence, glory, and fear. They definitely stand as the last bastions of an architectural style that reigned during a challenging era for Europe.
