Portable Sanctuary for the Celebration of the Catholic Mass:The city of Rome is home to over 900 churches in various states of use, each with its own unique character and sense of place. The same is true of the city's piazze, the urban hubs of the city. It is common, on religious holidays, for Mass to be celebrated outside to accommodate huge numbers of people.This sanctuary can be assembled in whichever piazza the Church sees fit. The tripartite, layered structure includes the dome, ciborium, and tabernacle consistent with Roman churches.
