It also borders on Lake Constance itself and the Swiss cantons of Thurgau and Schaffhausen . The Büsingen exclave on the Upper Rhine , which belongs to the district , also borders the Swiss canton of Zurich on a stretch of several hundred meters .


The district of Konstanz goes back to the old district office of Konstanz, which was established after the transition to Württemberg in 1805/06 (or from 1810 Baden ). The administrative structure of Baden in the Konstanz area was changed several times in 1809 (Seekreis), 1832 (Seekreis) and 1864 (District of Konstanz). In 1872 the Radolfzell district office was assigned to the Konstanz district. In 1936 the Engen district office was transferred to the Konstanz district office. In 1939 the district was changed slightly again and Konstanz itself became an independent city, but was reintegrated into the district in 1953. In 1969 the Hohentwiel Fortress and in 1967 the Bruderhof residential area in Singen came from the Tuttlingen district to the district area.

During the district reform in the state of Baden-Württemberg , the district of Konstanz was enlarged to its present size on January 1, 1973 to include most of the places in the dissolved Stockach district , three communities in the Sigmaringen district and Stetten in the Donaueschingen district . The west bank of Lake Constance , Höri and Hegau belong to the heterogeneously composed district . The election to the district council with 65 district councilors took place on April 8, 1973, the election of the district administrator on July 26, 1973.

Since the completion of the community reform , the district of Konstanz has comprised 25 communities, including seven cities, of which Konstanz , Radolfzell on Lake Constance and Singen (Hohentwiel) bear the title of large district town . The largest city is Konstanz, the smallest municipality is Büsingen am Hochrhein . As a German exclave, this is located between the Swiss cantons of Schaffhausen, Thurgau and Zurich, is a Swiss customs connection area and has its own distinctive sign for a vehicle .

About this picture

District and national border with Switzerland

Between the district of Konstanz and the canton of Schaffhausen in Switzerland there is an 84-kilometer border on the land side . Over 900 boundary stones mark their course. They are set so that one stone can be seen from the next. In 1893 the regulation was introduced that every six years German and Swiss officials conduct a joint inspection (cf. Schnadegang ). As a result, around ten to twenty copies are replaced, placed vertically again, cleaned or repainted. The border between the former state of Baden and Switzerland was regulated at the Congress of Vienna and marked in 1839. A boundary stone is 1.5 meters high, weighs 300 kilograms and has a cross-section of at least 30 cm.

There are various peculiarities in connection with the district of Büsingen .

The "old" district of Constance

Before the district reform in 1973 or before the community reform , the (old) district of Konstanz had a total of 66 communities since 1936 , including six towns , whereby the district town of Konstanz and the second largest town of Singen (Hohentwiel) had been large district towns since April 1, 1956 .

On March 7, 1968, the state parliament of Baden-Württemberg set the course for a community reform . With the law to strengthen the administrative power of smaller municipalities , it was possible for smaller municipalities to voluntarily unite to form larger ones. The beginning in the old district of Konstanz was made on January 1st, 1970 by the municipality of Duchtlingen, which merged with the municipality of Hilzingen . Further parish mergers followed, and on January 1, 1971, the parish of Nordhalden left the district of Constance because it merged with the city of Blumberg in the district of Donaueschingen . On April 1, 1972, the municipality of Beuren an der Aach was reorganized from the Stockach district and incorporated into the town of Singen (Hohentwiel) .

In the period that followed, the number of communities steadily decreased. On January 1, 1973, the new, enlarged district of Constance was established.

The largest municipality in the old district of Konstanz was the large district town of Konstanz . The smallest community was Talheim .

The old district of Konstanz last covered an area of ​​519 km² and had a total of 189,651 inhabitants at the 1970 census .

The table shows the population development of the old district of Konstanz up to 1970. All population figures are census results.
