世界で初めて建設されたカトリックの教会は何？
According to the "Catholic Encyclopedia" the Cenacle (the site of the Last Supper) in Jerusalem was the "first Christian church." "Archaeology" magazine suggests that the Dura-Europos church in Syria is the oldest surviving church building in the world. While Jordan's Aqaba Church is considered to be the world's first purpose-built church. Several authors have cited the Etchmiadzin Cathedral (Armenia's mother church) as the oldest cathedral.
