First up, altars (or ofrendas) are a huge part of Day of the Dead. Families create these beautiful displays in their homes or at gravesites with offerings such as flowers, candles, food, and photos of their loved ones. It's believed that these offerings help guide spirits back to the living world for a visit. Another tradition is La Catrina, a symbol representing death in Mexican culture. This elegantly dressed skeleton lady can be seen everywhere during the holiday, from parades to art displays.
