Lenzburg is a municipality in the district of Lenzburg in the canton of Aargau, Switzerland. It is the capital city of the district. The town was founded in the Middle Ages. It is in the Seetal valley, about 3 kilometres (1.9 mi) south of the Aare delta. Lenzburg and the municipalities of Niederlenz and Staufen have merged over time. The city name refers to the name of the castle which can be translated as spring castle.

As of 31 December 2010, Lenzburg about 8,341 people lived in Lenzburg. Lenzburg is about 30 kilometres (18.6 mi) west of Zürich. Many people living in Lenzburg go to Zürich to work.


The district of 1,113 ha (2,750 acres)in area is in a valley between two ranges of minor limestone mountains which rise about 100 m (328 ft) above the otherwise flat valley. The two major mountains are Während der Schlossberg at 504 m (1,654 ft) above sea-level with a diameter of only 250 m (820 ft), and the nearby Goffersberg at 507 m (1,663 ft) above sea-level which is only 500 m (1,640 ft) long and has a broad plateau 50 m (164 ft) wide. Lenzburg grew together with the nearby communities into a regional area

Nearby municipalities are Rupperswil in the northwest, Niederlenz and Möriken Wildegg in the north; Othmarsingen in the northeast, Hendschiken in the east, Ammerswil in the southeast, Egliswil the south, Seon in the southwest as well as Staufen in the west.


The area has a long history. A neolithic cemetery with 16 chambered tombs built about 3,800 years ago was found near the castle in 1959.

Lenzburg Theater Lindfeld
The Roman theatre at Lenzburg

A Roman theatre was uncovered when the motorway was built in 1964. It was built about 100 AD. It could seat an audience of about 4,000 people. It was part of a small village of 400 to 600 people that existed for about 200 years. The village was built on either side of the road for a distance of about 400 metres. There were shops, taverns, and small factories making wood and leather products. Behind these building were houses and farms. It is possible that there was a small fort in the village. The first buildings were wooden but these were destroyed in a fire at the end of the first century. The new buildings were made of stone. The village was abandoned in the 3rd century.

In the 5th and 6th centuries, an Alamanni village existed. The oldest registered usage of the name Lencis (from which Lenzburg derives) is from 893. In 1036, Castle Lenzburg became the seat for the count of Lenzburg, then an important lord. The family died out in 1173, and the castle was then owned by emperor Frederick Barbarossa. After this, it was mainly used by the Kyburger house. The Habsburgs took over the castle in 1273.

City rights were granted in 1306. Lenzburg was conquered by Bern in 1415, along with the western part of what is now Aargau. Bern did not take away its city rights. In 1433, the city of Bern bought the castle and used it to govern the area from 1444 to 1798. A major fire ruined the town in 1491. Only fifteen houses were not destroyed. The reformation was carried out at the same time with the rest of the region in 1528. The economy started to move slowly from a farming economy to a more industrial one in the 16th century. A textile factory was founded in 1732.

In 1798, the Helvetian Republic was made and the lords from Bern were removed. The canton of Aargau was founded and Lenzburg became the capital of the district in 1803. The canton gained the castle in 1804. Lenzburg became the economic center of the area in the 19th century. In 1875, Lenzburg was added to the railway system. Competition for trade became too much and Lenzburg became bankrupt only one year later. The town recovered from bankruptcy during the next 10 years.

In 1886, the German playwright, Frank Wedekind lived in the castle which his father had bought. It was sold in 1892 to August Edward Jessup from Philadelphia who spent a lot of money restoring the castle. He sold it to a Chicago banker, James W. Ellsworth in 1911. Ellsworth's son, Lincoln Ellsworth and Roald Amundsen used the castle to plan their polar explorations in the 1920s.
