Mirror Mirror on the pole......
A nano hidden out of plain sight but an easy "walk by" find. Be careful not to drop it in the drain!
This is a street of mainly landed houses. No high-rises here!
On the hill behind the cache are a few bushes and behind them (on private property) is a World War 2 pillbox, which is connected to an underground bunker. It's not known who the bunker belonged to but it's design is not typically British, so it may be a Japanese bunker. Whoever lived in this property in wartime must have been important as the bunker and pillbox are quite large.
