Several of the recent episcopal ordinations, including that today in Duluth, Minnesota, have been held in convention centers to allow greater attendance. This is a dreadful concession to modern sensibilities.
First, there is the matter of aesthetics. No matter how hard they try, these makeshift auditoriums tend to have an industrial look to them. They lack beautiful art of any kind, let alone religious art. Inevitably, an electronic organ provides the music, its whiny sound no substitute for the rich, round sound of a real pipe organ.
Second, there is the fact of human memory and how it is often evoked by location. When my mother died a few years ago, her funeral was in the church where she had been baptized, received her first communion, and was married. It was where she had buried her own parents. It was where her children were baptized. In short, merely walking through the doors of Our Lady of Lourdes church brought forth a host of human and holy memories.
