Christmas tree
In Norway, Christmas is an important family celebration, but the focus of the festivities and the opening of presents occurs on Christmas Eve. Christmas Day is something of an anti-climax. This is paralleled by events in the play. At the beginning of the play on Christmas Eve, Nora still believes her marriage to be happy. We see her ordering the Christmas tree to be brought in and insisting that it is hidden until she has decorated it. Symbolically, this alerts us to the fact that there are hidden aspects to life in this household, that a carefully created appearance is what matters, and that Nora is the keeper of appearances. Significantly, when she is trying to wheedle Torvald into keeping Krogstad in his job, she draws his attention to how pretty the flowers on the tree look.
