What is Sail Vault/Sail Dome

In the architectural work of Rafael Moneo, winner of the Pritzker Architecture Prize in 1996, geometry is a fundamental element, as he has confirmed through his writings and the very reality of his work. This chapter contains an analysis of the geometric component of his work, through his writings and interviews, but also through the drawings and models of his works that are most paradigmatic or most representative of his architectural style. Also analyzed are the possible influences from other architects and important works from the history of architecture. The conclusion is that the geometric component underlying his works has its roots in Platonic thought and that for Moneo, architectural ideas have an ontological nature, transcending the imperfection inherent in nature and approaching the perfection of Platonic order.
