The oldest known trace of early settlements in what is now Landsberg dates from the
Neolithic. It is first documented as
civitas holm in a 961 deed issued by King
Otto I of Germany, then located in the
Slavic lands beyond the southeastern borders of the
Duchy of Saxony along the
Saale River. Landsberg Castle from the 12th century onwards was the seat of the
Margraves of Landsberg. Held by the Saxon noble
House of Wettin, it was rebuilt when Margrave
Conrad of Meissen ceded the
March of Lusatia with Landsberg to his son
Theodoric I in 1156. A loyal follower of the
Hohenstaufen emperor
Frederick Barbarossa, Theoderic accompanied him on his
Italian campaign of 1176/77 against the cities of the
Lombard League and witnessed the peace negotiations leading to the
Treaty of Venice. Back in
Germany, he had a Staufian
double chapel erected on the Landsberg castle hill. Built in a
Romanesque style up on a cliff and visible even far from the town, it is one of Landsberg's landmarks up to today. When the Wettin margrave
Henry III of Meissen about 1258 re-established the Margraviate of Landsberg for his second son
Theodoric, Landsberg Castle had already lost its status as the margravial residence to
Weißenfels. Upon the death of Theoderic's son
Frederick Tuta in 1291, Landsberg fell to the
Ascanian margrave
Otto IV of Brandenburg. During decades of feuds between the Wettin and Ascanian dynasties the castle decayed and today only traces of wall remain. The settlement at the foot of the castle arose around the St Nicholas parish church dating from the 13th century. In 1579, the citizens of Landsberg were granted
town privileges by the
Saxon electors, though on condition not to erect city fortifications. Severely damaged during the
Thirty Years' War, the Landsberg double chapel about 1658/62 was restored at the behest of the Wettin duke
Christian I of Saxe-Merseburg. In 2019, two people were killed and two others were injured in a
terrorist attack in the city of
Halle. Two of the injuries occurred in the city of Landsberg. ==Coat of arms==
