The Architecture of Sacred Spaces: Exploring How form, Light and Materiality Shape Spiritual Experience in CatholicChurches in Ibadan, Nigeria

Abstract

This chapter examines the relationship between architectural design and spiritual experience in Catholic churches within Ibadan, Nigeria, with a focus on how spatial configuration, natural lighting, and materiality influence worshippers’ perception of sacredness. Using a quantitative research approach, data were collected from 102 respondents across multiple churches through a structured questionnaire comprising demographic, perceptual, and experiential variables. The data were analyzed using descriptive statistics, Pearson and Spearman correlation tests, and Analysis of Variance (ANOVA). The findings revealed that each architectural element investigated significantly contributes to enhancing spiritual experiences. Spatial configuration, particularly the altar’s location and the layout of interior spaces, was found to positively correlate with focus and reverence during worship. Natural lighting emerged as the most impactful factor, with a very strong positive correlation to spiritual upliftment, confirming that light is not only a functional element but a medium of divine symbolism. Materiality specifically the use of natural, textured, and symbolically meaningful materials such as wood, stone, and marble was also found to significantly shape the sacred atmosphere of the church interior. While minor differences in architectural perception existed across churches, ANOVA results indicated that these differences were not statistically significant, suggesting a broadly shared experience of sacredness among the respondents. These insights align with recent theoretical perspectives that integrate phenomenology, symbolism, and architectural determinism in sacred space design. The study concludes that thoughtful integration of spatial configuration, natural lighting, and materiality is essential for enhancing spiritual engagement, sacred perception, and emotional connection within Catholic worship environments. It recommends that architects and religious leaders work collaboratively to prioritize lighting, spatial harmony, and material symbolism in church architecture. Further research is encouraged to include qualitative methods and inter-denominational comparisons for a more comprehensive understanding of sacred architecture.
