Artificial Helsinki

Helsinki is indeed a very different city than it used to be and development is progressing rapidly. New construction sites are popping up and whole districts are being reorganised as areas around the centre convert from industrial zones to housing estates. But what was the shape of Helsinki’s core districts before the industrial expansion began?
From the map below you can see what was the original coast line, about a hundred years ago, in relation to the current, expanded shore (red shape). The west coast underwent the most dramatic changes with the west harbour and docks claiming a large portion of the coast line. So have areas around the Suvilahti power plant. Both are about to be transformed into expensive housing estates. The Katajanokka harbour has clearly generated some new land too and Töölönlahti has been shrinking significantly along the years. Notably part of what used to be a lake is now a large parking lot behind Finlandia Talo. (The comparison is approximate due to inconsistencies between the old and new maps.)

Following a request from Hugo I created another overlay with a map of Helsingfors dating back to 1815 in which the visible changes are even more dramatic. Back then there was nothing developed on Katajanokka yet and no railways nor stations existed.

Here’s a map from the Geological Survey of Finland that neatly shows the expansion of the shorelines along the years.
I received it from Johannes.

Here’s a map that Johannes created recently using all the gathered data.
