At one point in time, there were a total of 45 towers built into the walls that protected the city of Tallinn, Estonia. Twenty Six of those still remain. Two of the best preserved of the bunch are called Viru Gate. The gate dates from the 14th Century, as do most of the towers, and sits at the entrance way into the Old Town Sector of Tallinn. This old section of the city represents one of Europe’s only surviving medieval towns that still has fortified walls intact, so this is a history buffs place to visit.
