Every country has one

I recently saw an interesting post in a community where people discussed and chose different topics like the pictures here. On this occasion, I thought I would do the same for Estonia.

The rules are quite simple: every day (or at least I try to every day) I post an updated picture here together with the comment that received the most upvotes the previous day (the winner of the topic). So discuss and think about what these places, things and people could be here in Estonia.

Topic One: ICONIC LANDMARK
