A Christmas tree is a decorated tree that is typically an evergreen conifer, such as spruce, pine, or fir and is associated with the celebration of Christmas. The tradition of decorating a tree during Christmas dates back to the 16th century in Germany. Nowadays, Christmas trees are decorated with lights, ornaments, garlands, and a star or angel on the top. The tree is often placed in the living room and is surrounded by gifts during the holiday season. The Christmas tree has become a symbol of the holiday season and is widely recognized around the world.
