Can you name the 18 capital cities of European countries that are the least distance (or on) from the sea?
Inspired by a quiz by Georgekotz (Capitals Furthest From the Sea)
Measured on Google Earth.
Some may be on the sea by any meaningful way, but I'm measuring from the city center (where the name appears) in order to be decisive about what counts as the sea.
The answers with their distance in / / means that they might be on a body of water that connects to the sea, but it isn't really open ocean or there are many, many islands in the way.
