We have an unquenchable thirst to explore — to go beyond the known and to expand our knowledge of the universe. This thesis investigates sacred architecture as a setting that inspires reflection and contemplation, connecting humans to the knowledge that they seek. The design proposal consists of an obser¬vatory tower and underground chapels. The tower makes palpable the motion of the sun and the unchanging nature of the cosmos, while the underground chapels are designed as places for hermetic reflection the cultivation of a sense of presence through meditation, prayer or simple solitude. The project is a balance between traditional knowledge and contemporary architecture. Today, tradition is either marginalized as outmoded technology or fetishized as ‘heri¬tage’. In order to maintain tradition, it needs to be defended and explained. The design proposal explores the relationship between a human being and the universe — mediated by architecture, connected by light.
