The caches on this list are one way or another releated to the first world war fortress in and around Helsinki. Town was protected against the naval attacks by the coastal artillery batteries which located on the archipelago of the Helsinki district. On mainland areas town was surrounded with three consecutive fortress lines. Everywhere in the Helsinki district it can be found occasional trenches, shelters and fire positions. Today these locations are very much forgotten and covered by forests. Nevertheless (or should I say consequently) they are used extensively for caching purposes.
