What makes architecture extraordinary? Why are some urban spaces more vital and restorative? Wonderful landscapes, inspiring works of architecture and urban design, and the numinous experiences that accompany them have been an integral dimension of our culture. Up-lifting spaces, dramatic use of natural light, harmonic proportional geometry, magical landscapes, historic sites, and vital city centers create special, even sacred moments in architecture and planning. This quality of experience is often seen as an aesthetic purpose intended to inspire, ennoble, ensoul, and spiritually renew. Architecture and urban spaces, functioning in this way, are considered to be thin places.
