Pyrgos, a town in Greece, boasts 22 listed buildings and 61 protected structures, most of which exhibit neoclassical architecture. Architect Charis Mikelopoulos highlights the significant contributions of German architect Ernest Chiller, who designed various landmarks in the town. Despite its historical prominence as a cultural hub, Pyrgos has faced decline post-1870 due to economic changes and natural disasters. The loss of many historic structures is attributed to urban development and earthquakes, reflecting the ongoing challenges in preserving the town’s architectural heritage.
