[4] Windisch grew into a regional power following the foundation of Königsfelden Abbey in 1309 in memory of the regicide of King Albert I of Germany in the previous year.

Starting in 1348 the rights to high and low justice were held by Agnes of Hungary, a daughter of Albert I.

People from Windisch worked in the bailiff's residence as servants, maids and workmen, while the poor came to the former abbey for alms.

The main sources of income in Windisch included handicrafting, ferries, fisheries, shipping, tavern and iron ore mining in Lindhof, but agriculture was the major contributor.

The close proximity led to centuries of conflicts over grazing rights, city monopolies, taxation and especially the location of the municipal boundary.

In 1863, due to a border adjustment, Windisch lost 45 hectares (110 acres) to Brugg.

The construction of the railway network transformed Brugg and Windisch into a railroad hub with a large depot and repair shop (primarily for steam locomotives).

The changing population structure led to political shifts in favor of the Social Democratic Party (SP) (1921-49 was known as the period of the "red Windisch").

With a pronounced emphasis on political independence, Windisch grew together structurally and economically with Brugg.

22.4% of the total land area is heavily forested and 2.4% is covered with orchards or small clusters of trees.

[5] The municipality is located in the Brugg district, between the Aare and Reusss in the region known as the Wasserschloss.

It consists of the former linear villages of Windisch and Oberburg as well as the hamlets of Fahrgut, Schürhof, Lindhof and Bachtalen and the region around the former Königsfelden Abbey.

The blazon of the municipal coat of arms is Or on a Sevenfold Mount Vert a Castle embattled Sable towered on dexter and to its sinister a Lion rampant Gules.

The other large site is the church of the former Königsfelden Abbey with its glass paintings of 1325, Agnes chapel, comptrollery and convent building.

The other three are the former Upper Technical School at Klosterzelgstrasse, the former cotton mill Kunz at Alte Spinnerei 4,5 and the psychiatric clinic of Königsfelden.

[13] The city hosts a small Roman museum, displaying finds from the military fort of Vindonissa.
