In 1963 workers from a farm in the village of Letnitsa decided to build a new sheep house. While digging, at 50–60 centimeters, they came across a bronze vessel turned upside down. It was full of little silver items, some of them decorated with gold. They shared the treasure. Later on the curator of the museum of the near town of Lovech collected the items with the help of the doctor of the village, who witnessed the unearthing.

Save the silver items, some of which were very small, typical for the horse trappings from the 4th century BC, there was a well-preserved rein. It consisted of two iron braces, which were used to hold the bridle to the halter, and a bit-chain.

The cycle of illustrations of historic scenes on a group of plaques is very interesting. On some plaques the protagonist is represented as a horseman fighting and defeating bears and wolves, on other he is throwing his spear, followed by his servant.

The Letnitsa treasure plaques throw some light on the mythology of the ancient Thracians and their believes, which allows us to take a look at the culture and conception of world of these distant predecessors.

The Letnitsa treasure is exhibited in the National Archaeological Museum in Sofia.
