Roel Konijnendijk @roelkonijn.bsky.social · 20/09/2026Goryokaku (Five Point Fort) in Hakodate is a Japanese design of the 1850s, apparently by a man who had studied one book about European fortified cities (!). Note his excellent decision to add an extra ditch between moat and curtain. The original plan included five ravelins but only one was built. 1456
Roel Konijnendijk @roelkonijn.bsky.social · 18/09/2026Lake Tōya, a caldera lake on Hokkaido, is about 10km across. These small islands sit in the middle. Lake Tōya is a good ditch 2491

Roel Konijnendijk @roelkonijn.bsky.social · 14/05/2026A fun chat about many things to do with ancient warfare and its modern reception. Reconstructing ancient history requires imagination as well as research, and I tried to articulate the difference between "it is possible, but..." and "it is possible, therefore..." approaches to that fact 2313
