why do we put the christmas tree up

The tradition of putting up a Christmas tree is believed to have started in Germany in the 16th century. It is thought that people started decorating evergreen trees to celebrate the winter solstice and the birth of Jesus Christ. The tree became a symbol of new life, as it would stay green throughout the cold winter months. Today, the Christmas tree is a beloved part of the holiday season, and it is often used as a focal point for holiday decorations and activities.
