Schlosswil is a former municipality in the Bern-Mittelland administrative district in the canton of Bern in Switzerland.

During the Middle Ages, a fortress (German: Burg Wil) was built near the village and it became the seat of the Herrschaft of Schlosswil.

The territory was split in half and passed through several Bernese patrician families until Burkhard von Erlach reunited the two halves in 1514.

Shortly thereafter it was rebuilt as a larger castle under the direction of the master builder Niklaus von Wattenwyl-May.

The current appearance comes from a 1780 renovation that gave the castle a Baroque exterior.

However, about three-quarters of the working population commutes to jobs in Bern, Thun or other nearby cities.

Of the rest of the land, 0.31 km2 (0.12 sq mi) or 9.0% is settled (buildings or roads).

It consists of the village of Schlosswil, the settlement of Thali and the hamlets of Öli, Weiergut and Untere Mühle.

On the following day, 1 January 2010, it joined the newly created Verwaltungskreis Bern-Mittelland.

[12] Most of the population (as of 2000[update]) speaks German (639 or 97.4%) as their first language, Serbo-Croatian is the second most common (7 or 1.1%) and French is the third (3 or 0.5%).

The historical population is given in the following chart:[4][17] The Castle and surrounding park is listed as a Swiss heritage site of national significance.

In the tertiary sector; 2 or 2.2% were in wholesale or retail sales or the repair of motor vehicles, 15 or 16.9% were in a hotel or restaurant, 12 or 13.5% were technical professionals or scientists, 8 or 9.0% were in education.

[12] From the 2000 census[update], 511 or 77.9% belonged to the Swiss Reformed Church, while 40 or 6.1% were Roman Catholic.

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

Following the lower Secondary students may attend additional schooling or they may enter an apprenticeship.

[22] During the 2011–12 school year, there were a total of 74 students attending classes in Schlosswil.
