Roggenburg is a municipality in the district of Laufen in the canton of Basel-Country in Switzerland.

[3] The name originates from the Latin word rogus (stake; funeral pyre; stack of logs).

Roggenburg belonged to the Count of Thierstein and was then handed over to the Roman Catholic Diocese of Basel in 1454.

In 1815, the Congress of Vienna declared that the area would become part the district of Delémont within the Canton of Bern.

On 7 September 1975, the inhabitants voted to remain part of the canton of Bern.

Therefore, in 1976 the municipality became part of the administrative district of Laufen, which has been an exclave of Bern since Jura was founded on 1 January 1979.

Roggenburg itself remained of the opinion to stay with Bern, but in the second referendum the overall district voted marginally to join Basel-Country.

However, such a small community had no persuasive power over the opinion of the rest of the district, and on 1 January 1994 Roggenburg became part of the canton of Basel-Country.

The current parish church of Sankt Martin was constructed in 1635 in the late gothic style.

To the north, the village confines extend to the bank of the river Lützel (French: Lucelle), in the hilly landscape of the northern Jura Mountains.

Of the rest of the land, 0.21 km2 (0.081 sq mi) or 3.2% is settled (buildings or roads), 0.01 km2 (2.5 acres) or 0.2% is either rivers or lakes.

On the eastern boundary of the municipality, the Lützel drains into the river Birs, a significant tributary of the Rhine.

Roggenburg encompasses the hamlets of Sägemühle (in the Lützel valley) and Neumühle (French Moulin-Neuf), which lies east of the Bösen, as well as numerous individual farmsteads.

[8] Most of the population (as of 2000[update]) speaks German (221 or 94.0%), with French being second most common (7 or 3.0%) and Italian language being third (1 or 0.4%).

[7] The age distribution, as of 2010[update], in Roggenburg is; 17 children or 6.1% of the population are between 0 and 6 years old and 43 teenagers or 15.4% are between 7 and 19.
