Sacral architecture

Sacral architecture—also called sacred or religious architecture—involves designing and building spaces meant for worship or other intentional sacred purposes, including churches, mosques, stupas, synagogues, and temples. Across many cultures, vast resources have been poured into these structures, which rank among humanity’s most striking and durable monolithic buildings. Yet sacred architecture can also take non-monolithic, fleeting, and intensely private forms, serving as a setting for personal, non-public intimacy.

Religious and holy buildings often evolved over centuries and, before the modern skyscraper, were the largest structures in the world. Although the styles used in sacred architecture sometimes mirrored trends in other buildings, they also remained distinct from the contemporary architecture of secular structures. With the spread of Christianity and Islam, religious buildings increasingly became centers for worship, prayer, and meditation. The Western academic discipline of architectural history itself closely follows the history of religious architecture from ancient times through at least the Baroque period. Sacred geometry, iconography, and the use of sophisticated semiotics—such as signs, symbols, and religious motifs—are inherent to sacred architecture.

Sacred or religious architecture is sometimes referred to as sacred space. Architect Norman L. Koonce has proposed that its goal is to “make transparent the boundary between matter and mind, flesh and the spirit.” Protestant minister Robert Schuller suggested that, for psychological health, humans need to experience their natural setting—the garden we were designed for. Richard Kieckhefer argues that entering a religious building is a metaphor for entering a spiritual relationship. He identifies three factors affecting spiritual process in sacred space: longitudinal space emphasizes the procession and return of sacramental acts; auditorium space suggests proclamation and response; and new forms of communal space designed for gathering and return rely heavily on minimized scale to enhance intimacy and participation in worship. Scholar Florin George Călian affirms that “the sacred space is the place where the transcendent becomes immanent, and where the devotee can access God.”

Sacred architecture includes many ancient styles, such as Neolithic, ancient Egyptian, and Sumerian architecture. Ancient religious buildings—especially temples—were often seen as the dwelling place, or temenos, of the gods and served as sites for various sacrifices. Ancient tombs and burial structures also reflect the religious beliefs of their societies. The Temple of Karnak at Thebes, Egypt, was built over 1,300 years, and its many temples may form the largest religious structure ever constructed. Ancient Egyptian religious architecture has fascinated archaeologists and captured the public imagination for millennia.

Around 600 BCE, the wooden columns of the Temple of Hera at Olympia were replaced with stone ones. As this practice spread to other sanctuaries, a few stone buildings survived through the ages. Because temples are the only buildings that survive in numbers, most of our understanding of classical architecture is based on religious structures. The Parthenon, which served both as a treasury and a place for venerating a deity, is widely regarded as the greatest example of classical architecture.

Indian architecture is shaped by the history and religions of its time periods, as well as by the geography and geology of the subcontinent. India was crossed by trade routes from as far away as Siraf and China, and it weathered invasions by foreigners, leading to multiple foreign influences on native styles. The diversity of Indian culture is reflected in its architecture, which blends ancient and varied native traditions with building types, forms, and technologies from West, Central Asia, and Europe.

Buddhist architecture developed in South Asia starting in the third century BCE. Two types of structures are linked to early Buddhism: viharas and stupas. Originally, viharas were temporary shelters used by wandering monks during the rainy season, but they later evolved to accommodate the growing and increasingly formalized Buddhist monasticism. An existing example is at Nalanda in Bihar. The stupa’s initial function was to venerate and safeguard the relics of the Buddha. The earliest existing stupa is in Sanchi, Madhya Pradesh. As religious practice changed, stupas were gradually incorporated into chaitya-grihas (stupa halls), which reached their high point in the first century BCE, as seen in the cave complexes of Ajanta and Ellora in Maharashtra. The pagoda is an evolution of the Indian stupa, marked by a tiered tower with multiple eaves, common in China, Japan, Korea, Nepal, and other parts of Asia. Buddhist temples were developed later and mostly outside South Asia, where Buddhism gradually declined from the early centuries CE onward, though an early example is the Mahabodhi Temple at Bodh Gaya in Bihar. The stupa’s architectural structure spread across Asia, taking on many diverse forms as regional details were incorporated into the overall design.
