My son and his (now) wife chose to have a wedding at the Holy Spirit Pregnancy Church. Although I worked in the city center, I never stopped to visit it. My husband and I visited this church a few months before our wedding and it was a place where people's hearts were purified. The church has so much history that I was impressed by the ironwork on the back of the bench. Regarding the wedding, we stayed at the hotel on the corner next door and our room was right next to the bell tower. So pure and lovely. St. Louis Cathedral does have a lot of attraction, but the Holy Spirit Pregnancy Church should also be on your tour list.
