It really is remarkable that within the same city there is another state like the Vatican, a very different world but similarly reflected in all of Rome. Wherever you go, you see the figure of a priest or nun. The Plaza de San Pedro is splendid, with its columns, its two fountains and huge domes. Every detail in it is worthy of admiration. Similarly when you enter the Basilica of St. Peter, you can not help but appreciate the perfection, splendor, wealth and careful maintenance of both the structures and objects. I have no problem with the dress requirements as it is a place of worship.
