Gymnasium Carolinum (Osnabrück)

St. Peter's Cathedral in Osnabrück, Germany is the cathedral of the Roman Catholic Diocese of Osnabrück. The cathedral is a late Romanesque building and dominates the city's skyline.

The Diocese of Osnabrück is a Latin Church ecclesiastical territory or diocese of the Catholic church in Germany. The diocese was originally founded circa 800. It should not be confused with the smaller Prince-Bishopric of Osnabrück–an ecclesiastical principality of the Holy Roman Empire until 1803–over which the bishop, as prince-bishop, exercised both temporal and spiritual authority.

Theater Osnabrück is a German theatre in Osnabrück, Germany. It operates under the auspices of the Städtische Bühnen Osnabrück gGmbH. The primary performance venues are the Theater am Domhof (seating capacity 642) and the emma-theater (seating capacity 96). The roots of the company date back to 1771, with theatrical presentations at the Schloss Osnabrück. In 1780, productions shifted to two former aristocratic residences. Albert Lortzing had an official affiliation with the company from 1827 to 1833. In 1832, the city of Osnabrück took over the complex as its first municipal theatre. From 1905 to 1909, the main theatre was built. On 29 September 1909, Julius Caesar was the first play to be staged at the newly completed theatre. The Domhof building suffered damage from bombing in 1945 during World War II. British military authorities banned theatrical performances after the war, lifting the ban in July 1945. Reconstruction and restoration of the Domhof began in 1949, and was completed in 1950. Since 2011, Ralf Waldschmidt has served as Intendant of the theatre. Since 2012, the company's Generalmusikdirektor (GMD) has been Andreas Hotz.

Osnabrück Land (German: Osnabrücker Land) is a region in southwest Lower Saxony in Germany, which extends into the state of North Rhine-Westphalia. Its centre is the city of Osnabrück. The region is dominated by the Teutoburg Forest and the River Hase. Originally a variant of Low German was spoken here which belonged to the East-Westphalian dialect. The region is generally identified with the district and city of Osnabrück, which largely corresponds to the Prince-Bishopric of Osnabrück in the Holy Roman Empire. The Osnabrück Land Regional Association (Landschaftsverband Osnabrücker Land) looks after cultural issues for the region.

St. Marien (St. Mary's Church) is a Lutheran parish and market church in Osnabrück, Germany. It is one of the most artistically and historically significant buildings in the North German city. A previous Romanesque church was mentioned in records as early as 1177. However, the history of the church's construction began some time before it was first mentioned in writing. Archaeological traces suggest the existence of a predecessor building in the 10th century. Construction of the Gothic hall church which exists today started in the 13th century and was completed between 1430 and 1440. The St. Marien church has a complex architectural history. Over time, extensive restorations have enabled archaeological excavations which have contributed considerably to a reconstruction of the building's history. The existence of at least three predecessor buildings has thereby been established. As Osnabrück's oldest town church, it has a central location in the city. The Marienkirche is located directly on the market place, next to the Stadtwaage (city weighing house) and the town hall. Along with the cathedral, St. Katharinen (St. Catherine's) and St. Johann (St. John's), it is one of the four medieval churches which encompass the Innenstadt (city centre) of Osnabrück.

The historic town hall (Rathaus) of Osnabrück, Germany was built in the late Gothic style from 1487 to 1512.

The Treaty of Westphalia was negotiated and signed by the combatants of the Thirty Years’ War at the town halls of Osnabrück and Münster in 1648.
