If you want to take a journey through the country's history, visit these barracks behind Nevski Cathedral. They remain here from the sixteenth century and are are now open to the public after a period of restoration. The revolutionaries and rebels who fought for the freedom of the country were arrested here in 1876. Among them was the pacifist Vasil Levski, a national hero, who was killed at this site. The barracks now represent all of those men who fought to be free. You can enter the barracks as they´re only closed by a gate. They aren´t very big, and probably dozens of prisoners were crammed here together.
