Battle on the Planta (Switzerland)

The Battle on the Planta, fought on 13 November 1475 around Conthey near Sion, Valais, Switzerland, was part of the Burgundian Wars.



In the 13th and 14th centuries, the Upper Valais (the eastern portion of the valley, higher in the mountains) was colonized by Germans from Hasli in the Canton of Bern. The Upper Valais was loosely allied with the Swiss, especially with Bern. The Lower Valais (the western, lowlands of the valley) were inhabited by French speakers under the power of the Dukes of Savoy. During the early and mid 15th century conflicts between the Upper Valais and Lower Valais often led to fighting. In 1446 Bern and Savoy signed a peace treaty, though border conflicts over the following decades damaged the agreement. In 1473 Duchess Yolande of Savoy embargoed Bern. [1]

The battle

In 1475 Bern invaded Vaud, a Savoy province, and signed an alliance with the Upper Valais on 7 September 1475. [2] With Bernese support the Upper Valais prepared for war. Led by the Bishop of Sion Walter Supersaxo the Upper Valais forces began attacking Savoy holdings. A Savoy counterattack in early November threatened the city of Sion. On 13 November the Bishop's forces together with unexpected reinforcements from Saanen, the Simmental, Fribourg, and Solothurn defeated the Savoy counterattack near Conthey to the west of Sion. [3]


Following the Savoy defeat at the battle, the bishop's army marched west conquering the Lower Valais as far as Saint-Maurice and capturing a total of 17 Savoyard castles. [1] The towns of Conthey and Saint-Maurice were garrisoned by Bern and Fribourg and Savoy was cut off from Italy. [3] In 1477, the bishop annexed much of the Lower Valais, though it was not accepted by Savoy until 1528. [1] The Confederate support strengthened the ties between Valais and the Swiss Confederation.

Early history of Switzerland History of Switzerland to 1291

The early history of Switzerland begins with the earliest settlements up to the beginning of Habsburg rule, which in 1291 gave rise to the independence movement in the central cantons of Uri, Schwyz, and Unterwalden and the Late Medieval growth of the Old Swiss Confederacy.

Growth of the Old Swiss Confederacy

The Old Swiss Confederacy began as a late medieval alliance between the communities of the valleys in the Central Alps, at the time part of the Holy Roman Empire, to facilitate the management of common interests such as free trade and to ensure the peace along the important trade routes through the mountains. The Hohenstaufen emperors had granted these valleys reichsfrei status in the early 13th century. As reichsfrei regions, the cantons of Uri, Schwyz, and Unterwalden were under the direct authority of the emperor without any intermediate liege lords and thus were largely autonomous.

The ruins of the Gestelnburg castle are situated above the village of Niedergesteln in Valais, Switzerland, on a rocky ridge called Feschti. The castle was probably built during the 12th century by the powerful Barons de la Tour, which are also called in German Herrn vom Turn. The rule of this family ended during the wars against the bishop of Sion in the second half of the 14th century, and the castle was finally destroyed by the Upper Valaisans in 1384. Exactly 600 years later, a project was started to restore the ruins and make them more easily accessible. Behind the castle there is a cave called Feschtiloch, which originates from the last ice age.
