The Fortress Ring


A collection of sites dedicated to military fortification in the period 1450 to 1950. Individual sites are concerned either with a single fortification, fortress systems [Maginot Line etc.], famous engineers, siege warfare, or the theory of fortress design and armament. Ring sites come in various languages, but all are well illustrated. So that, even without understanding the text, each site is well worth a visit.

Outdoor, travel and history site by two retired Boomers, one a retired Marine. It combines geocaching and related activities with history, travelogues, tips and commentary. Our quests include historical sites, forts, battlefields, ghost towns, parks, urban exploration and back country wilderness. We seek out little known places or events to explore and write about. The more challenging or remote they are, the better we like it. We hope to promote lifelong learning and curiosity about our world, especially in young people. If you are looking for ideas to teach and motivate kids, get them active outside and have some fun together, this site offers a lot. There's no armchair traveling. We've been to every place on these pages. The pictures and content are ours. Most of it is Off the Beaten Path.
