In some parts of Ireland, Brittany and Germany there were fairy or spirit paths that while being invisible nevertheless had such perceived geographical reality in the minds of the country people that building practices were adapted to ensure they were not obstructed. A significant number of the characteristics of fairy paths are shared in common with
ley lines. In many parts of Northern Europe the
round barrows were the traditional homes of the
fairies,
elves, or
trolls and were avoided by the country folk. Such places were Fairy Toot in
Somerset, Elf Howe barrow near
Folkton, Yorkshire, and a round barrow at
Beedon in Berkshire.
Cornwall was and is a stronghold of fairy lore: fairies are said to dance on
Carn Gluze, near
St Just in Penwith. In Danish
Jutland there was a belief that "Barrow-folk" dwelt in barrows and were descendants of
fallen angels cast out of
Heaven. Likewise, it was considered bad luck to let cattle graze on any place where the Elf-folk have been, or to let the cattle mingle with the large blue cattle of the elves. However, all evils may be averted if one were to ask at an "Elf-barrow" for permission to graze cattle on their mound. In Germany the
Wild Troop of Rodenstein was said to ride a straight path between the castles of Rodenstein and Schnellert. Also throughout Europe are
Corpse roads, which are generally believed to be of the same basic belief as
fairy paths and most likely share an origin. In Germany and the
Netherlands in particular, these tend to be straight invisible lines and are known by a variety of names including
Geisterweg ("ghost-way" or "ghost-road") and
Helweg ("hell-way" or "hell-road") in German and
Doodweg ("death-way" or "death-road") in
Dutch. A similarly straight road did however run straight over various burial mounds at Rösaring,
Lassa in southern Sweden. ==Consequences of blocking fairy paths==
