Resumen: This article offers the architectural definition and interpretative keys to a unique project. It is a space shared by the three main Abrahamic faiths: the Jewish, Christian and Muslim religions. Although conceptually other religions could be accommodated. Its configuration is very elementary: a cubic volume, massive and almost blind, with a cylindrical space crowned by a simple skylight. Each of the religions is based on a scratching of the interior surfaces of the space, forming the ritual areas of each of them. And towards the center of the space there are other areas of prayer and celebration that could be shared among the believers of the different religions, from the conviction that they are addressed to the same God. In this configuration there is a will of invitation, of offering to all men of good will. The article, written by the architect of this space, mentions some plastic and conceptual references that have served as inspiration for the project and its presentation is intended to fuel the debate on the possibility of this space.
