University students of architecture will explain to you that today, in their university programs of study, classical architecture is still "forbidden."
So parish building committees and architectural firms continue to build the most discordant places of worship one can imagine (even in Catholic countries such as Italy, Poland, Spain, etc).
Here's a fine church which could be reproduced with ease anywhere and on budget. If you're on the parish building committee than consider this one in La Storta, just northwest of Rome with its attached school and rectory (p.s. Eugene Cardinal Tisserant is buried here).
