Tholos vs Rotunda is a comparative architectural design study that examines two distinct yet related circular building forms originating from different historical periods and cultural contexts. The Tholos, emerging from ancient Greek architecture around the 7th century BCE, represents a circular temple structure characterized by a colonnade surrounding a central cella, typically crowned with a conical or domed roof, while the Rotunda, developed during the Roman period and extensively used throughout architectural history, describes a round building or room covered by a dome, often featuring a more enclosed and substantial wall structure. This architectural comparison illuminates the evolution of circular design principles, where the Tholos emphasizes external columnar rhythm and religious functionality, commonly seen in sacred Greek sanctuaries, while the Rotunda demonstrates a more versatile spatial approach, frequently employed in civic, religious, and commemorative architecture. The fundamental distinction lies in their structural composition and spatial organization: Tholoi (plural of Tholos) typically maintain an open, permeable relationship with their surroundings through their peripteral column arrangement, whereas Rotundas often present a more massive, enclosed form with potential for larger interior spaces and more complex dome configurations. These circular architectural forms have significantly influenced contemporary design practices, particularly in projects submitted to prestigious competitions such as the A' Design Award, where architects continue to explore and reinterpret these classical forms through modern materials and construction techniques, demonstrating the enduring relevance of these ancient architectural typologies in addressing contemporary spatial and aesthetic challenges.

Tholos vs Rotunda is a comparative architectural study that examines two distinct circular building traditions from ancient Greek and Roman design heritage, highlighting the evolution of round temple architecture across classical civilizations. The Greek tholos, emerging in the 7th century BCE, was characterized by its circular plan, peripteral colonnade, and conical roof, typically serving religious or commemorative functions, with notable examples featuring sophisticated Doric or Corinthian orders and intricate stone craftsmanship. In contrast, the Roman rotunda, exemplified by architectural masterpieces dating from the 1st century BCE onwards, represented an advancement in spatial and structural design, incorporating the revolutionary Roman concrete technology that enabled the construction of larger, unobstructed interior spaces crowned by magnificent domes. The fundamental distinction lies in their spatial organization: while the tholos emphasized external ceremonial circulation through its peripheral colonnade, the rotunda prioritized internal spatial experience through its grand domed interior. This architectural evolution reflects broader cultural shifts from Greek emphasis on external formal perfection to Roman focus on interior spatial innovation. The technical achievements in both forms continue to influence contemporary circular building design, particularly in civic and cultural architecture, where their principles are regularly featured in projects submitted to prestigious competitions such as the A' Design Award. The development from tholos to rotunda represents a crucial transition in architectural thinking, from the Greek conception of buildings as sculptural objects to the Roman understanding of architecture as shaped space, marking a fundamental shift that would influence Western architectural design for millennia.
