Lenzburg Castle
Lenzburg Castle sits atop a nearly circular hill above the town of Lenzburg in the Canton of Aargau, Switzerland. It is one of the country's oldest castles, formed of a cluster of stone buildings, gatehouses and curtain walls arranged around an inner bailey and enclosed by high defenses on the steep southern and eastern cliffs.

The shape it held in its prime.
Perched on a nearly circular limestone hill about 100 m above the plain, the castle is a compact complex of connected stone buildings and curtain walls arranged in a rough horseshoe around an inner bailey. Steep red clay-tiled gabled roofs cap long rectangular ranges; a multi-storey square keep and gatehouses rise above lower service buildings. Thick pale-grey masonry curtain walls follow the cliff edge, enclosing a paved central courtyard with mature trees and a formal enclosed garden on the southwest.
Its story
The story of Lenzburg Castle.
The oldest parts of Lenzburg Castle date to the 11th century, when the Counts of Lenzburg built it as their seat on the almost circular castle hill above the town — a charter of 1036 names one Ulrich, Count of Aargau. The counts ranked among the most important feudal lords on the Swiss plateau and maintained close connections to the emperor.
Ulrich IV, the last Count of Lenzburg, named Emperor Frederick Barbarossa — his companion on the Second Crusade — as his personal heir. The emperor came to Lenzburg in person to supervise the division of the estate, giving the majority of the lands to his son, the Count palatine Otto of Burgundy; after Otto's death in 1200 the House of Hohenstaufen was forced to withdraw from the Aargau.
By way of two neighbouring aristocratic houses, Andechs-Merania and Chalon, the castle came by marriage to the Counts of Kyburg in about 1230. When Hartmann, the last Count of Kyburg, died without male issue in 1264, Rudolph of Habsburg placed the heiress Anna of Kyburg under his protection, and she later married Eberhard I of Habsburg-Laufenburg. The castle ranks among the oldest and most important in Switzerland, and houses a historical museum.
