Opening onto the Baltic sea, to the far north of Estonia, the town of Tallin will win you over with the picturesque charm of its architecture. You can meander through its little streets in the heart of the medieval centre where its gothic town hall has been standing since 1404. The Kiek in de Kök tower, the Orthodox Alexander Nevski cathedral, or Toompea castle give visitors a taste of this town’s rich past. The city was particularly active during the medieval period, as is demonstrated by the very beautiful monuments from this period that are still visible. Don't hesitate to lose yourself in the heart of Tallinn, listed as a UNESCO World Heritage Site.
