Funeral Ceremonies can be conducted anywhere! However, most will be in a crematorium or burial ground; whether a cemetery or a natural/woodland burial ground.
If you would prefer a ceremony not governed by a 'time slot' there are other options you could consider. As long as your chosen venue is happy to have the coffin present then you could have your ceremony in your home or garden, an hotel, village hall, field, beach - the list is endless.
Many people are now choosing a funeral ceremony in a crematorium attended by a few people; family and closest friends, followed by a Memorial or Celebration of Life Ceremony on a different day.
