The Christmas tree is a decorated evergreen coniferous tree, real or artificial, and a tradition associated with the celebration of Christmas or the original name Yule. The Christmas tree is often brought into a home, but can also be used in the open, and can be decorated with Christmas lights (originally candles), ornaments, garlands and tinsel during the days around Christmas. An angel or star is often placed at the top of the tree, representing the host of angels or the Star of Bethlehem from the Nativity.
