mainly German and many official publications of the canton are available only in German, it is virtually impossible for a municipal administration to operate only in Romansh. Romansh in education Within the Romansh-speaking areas, three different types of educational models can be found: Romansh schools, bilingual schools, and German schools with Romansh as a subject. In the Romansh schools, Romansh is the primary language of instruction during the first 3–6 years of the nine years of compulsory schooling, and German during the last 3–9 years. Due to this, this school type is often called the "so-called Romansh school". In practice, the amount of Romansh schooling varies between half and 4/5 of the compulsory school term, often depending on how many Romansh-speaking teachers are available. This "so-called Romansh school" was found in 82 municipalities of the Grisons as of 2001. The bilingual school was found only in Samedan, Pontresina, and Ilanz/Schnaus. In 15 municipalities, German was the sole medium of instruction as of 2001, with Romansh being taught as a subject. Outside of areas where Romansh is traditionally spoken, Romansh is not offered as a subject and as of 2001, 17 municipalities within the historical language area of Romansh do not teach Romansh as a subject. On the secondary level, the language of instruction is mainly German, with Romansh as a subject in Romansh-speaking regions. Outside of the traditional Romansh-speaking areas, the capital of the Grisons, Chur, runs a bilingual Romansh-German elementary school. On the tertiary level, the University of Fribourg offers Bachelor- and Master programs for Romansh language and literature. The Romansh department there has been in existence since 1991. The University of Zürich also maintains a partial chair for Romansh language and literature together with the ETH Zürich since 1985. Geographic distribution Whereas Romansh was spoken as far north as Lake Constance in the early Middle Ages, the language area of Romansh is today limited to parts of the canton of the Grisons; the last areas outside the canton to speak Romansh, the Vinschgau in South Tyrol, became German-speaking in the 17th century. Inside the Grisons, the language borders largely stabilized in the 16th century and remained almost unchanged until the 19th century. This language area is often called the "Traditional Romansh-speaking territory", a term introduced by the statistician Jean-Jacques Furer based on the results of the Swiss censuses. Furer defines this language area as those municipalities in which
