Catholics may have a special place in their homes designated as the family altar.
This is mentioned many places:
In contradistinction to the typical home which has a television set as its centerpiece, the focal point of a Catholic home should be the family altar -- a place where the family can gather to offer up their prayers to the Most Holy Trinity and to ask the Saints to pray for them. Morning Offerings, family Rosaries, prayers for special intentions, family novenas, Lectio Divina, etc., can all be made here. source emphasis added

Are there any non-Catholic traditions that do a similar sort of thing? If so, what is the purpose of having a family altar, and what do they typically put on it?
