England is a country that is a part of the United Kingdom and shares land borders with Scotland to the north and Wales to the west.

England’s terrain mostly comprises low hills and plains, especially in central and southern England.

Christianity is the most widely practised religion in England as it has been since the Early Middle Ages.
