We visited Tallinn, the capital of Estonia and it was a good surprise, we found a medieval center in great condition, very cozy and with old churches and buildings all weel preserved.
Tallinn is the largest city in Estonia and the most developed city in the Baltic countries, is a developed city with the largest number of startup per person in Europe.
I suppose it was not always the case, but for a few years now, Tallinn has become a very popular city for tourists, mainly from that part of Europe, due to its unique medieval atmosphere, its historical center, which is one of the best we saw in Europe.
