What the Helsinki app is meant to be used on location and smart watches will make that much easier. You can always see the nearest images on your wrist instead of constantly getting your phone out of your pocket.
The next Android version will have support for smart watches and it’s almost ready. A simple Apple Watch version also exists on my computer but I don’t yet have a watch myself so that I could test it.
Should the historically significant waterfall of a working museum power plant be preserved or should the dam be demolished to recreate one kilometer long rapids that once were at the location where Helsinki was originally founded?
There’s a very sad book about unique but demolished buildings in Helsinki. The significance of these buildings wasn’t always understood at the time. I’d put the matter on hold to avoid a new tragedy. Demolition is final but nature can wait another 10 years.
