In Scandinavian Lutheran doctrine, the ashes are to be dealt with the same dignity as any earthly remains. They are either to be interred in an urn in a cemetery or sprinkled on consecrated ground, "dust returning to dust," and not stored at home or disposed of in an undignified way. Several littoral parishes do also have consecrated sea areas where the ashes may be sprinkled. Also unmarked "groves of remembrance" (tens of thousands of people buried within an area of 10–50 common graves with a common memorial) have become a common way of burial. Often the undertakers recommend cremation to the mourners. Cremation has also seen the re-appearance of the traditional Scandinavian family graves, where one single grave plot may now contain dozens of urns of the members of the family in several generations. Many Scandinavians prefer their ashes to be interred alongside their family members and loved ones.
