Christianity is one of the oldest religions in the world currently. In the early years of Christianity, there were no churches as the early Christians had their meetings in the homes of some members.
As the religion grew, the early Christians saw the need to build places of worship, and some of these places date as far back as the 1st century. We would be looking at some of these churches that have existed all these years.
