The castle, the home of the Lords of Bremgarten, was located at a narrow point on the Aare peninsula.

The castle was the center of a barony that stretched along the Aare river at least as far as from Worblaufen to Kirchlindach.

[3] In 1298, the town and castle were destroyed by Bern after the Bernese victory at the Battle of Donnerbühl.

In 1306, the Lords of Bremgarten sold their land, rights and their ferry, to the Knights Hospitaller commandry of Münchenbuchsee.

In 1545, Bern sold the village and low court right to the Schultheiss Hans Franz Nageli.

He demolished the old castle, except for the keep and curtain walls, and had a renaissance country manor built.

Over the following centuries the castle and land was repeatedly inherited, bought and sold by Bern's patrician families.

In 1743-47 the medieval keep and ramparts of the castle were demolished to make way for a baroque summer palace.

Starting in 1765, the new owner Albrecht von Frisching, encouraged many tenants and craftsmen to settle in Bremgarten to help him rebuild the castle.

[4] In 1770-71 the country estates of Belvedere (Friedrich von Luternau) and Aarwyl (Rudolf Albrecht Haller) were built in Bremgarten.

[3] During the 19th century, Bremgarten Castle changed hands frequently, until 1918 when it was bought by the wealthy industrialist Wassmer family.

After the 1798 French invasion and under the Helvetic Republic, Bremgarten was granted a town council and became part of the District of Bern.

However, the town remained isolated from the major roads leading to Bern until the 20th century.

[7] The municipality is located in the agglomeration of Bern on the right bank of the Aare river.

It consists of the village of Bremgarten bei Bern and the neighborhoods of Seftau-Ländli, Äschenbrunnmatt, Kalchacker, Stuckishaus-Neubrügg and Bündacker.

[8] The blazon of the municipal coat of arms is Per fess pally of six Argent and Sable and barry of six of the same.

[12] Most of the population (as of 2000[update]) speaks German (3,508 or 92.3%) as their first language, French is the second most common (75 or 2.0%) and Italian is the third (41 or 1.1%).

The historical population is given in the following chart:[3][15] The Castle is listed as a Swiss heritage site of national significance.

In the tertiary sector; 61 or 18.0% were in wholesale or retail sales or the repair of motor vehicles, 9 or 2.7% were in a hotel or restaurant, 19 or 5.6% were in the information industry, 6 or 1.8% were the insurance or financial industry, 39 or 11.5% were technical professionals or scientists, 43 or 12.7% were in education and 70 or 20.7% were in health care.

This is followed by three years of obligatory lower Secondary school where the students are separated according to ability and aptitude.

[21] During the 2009-10 school year, there were a total of 430 students attending classes in Bremgarten bei Bern.
