FREIBURG or FREYBURG, a city in the grand duchy of Baden, capital of the circle of the Upper Rhine, on the Dreisam, and on the Basle and Mannheim railway, 40 miles N. by E. of the former town. The town is generally well-built, having several wide and handsome streets and some squares. Its old fortifications have been replaced by fine public walks and vineyards. It is the seat of an archbishop, and has a Catholic university founded in 1457, with a library of 100,000 volumes, a botanic garden, and a museum of natural history. Among the public buildings are the palaces of the grand duke and the archbishop, the custom-house, exchange, theatre, town-hall, museum, house of correction, &c. The charitable establishments include a foundling hospital, orphan asylum, military hospital, and a blind asylum. The cathedral or minster is considered one of the finest and most perfect specimens of Gothic architecture in Germany, being alike remarkable for the delicate symmetry of its proportions and the good taste of its decorations. It was begun towards the middle of the twelfth century, and was not completed till 160 years afterwards. The tower is 386 feet high, exhibiting a skilful transition from a square base into an octagon, which is surmounted by a pyramidal spire of the most exquisite open-work tracery of stone, of extreme boldness as well as lightness. The edifice is of red sandstone, and contains some stained glass-windows of great beauty, statues of Berchtold V., and other dukes of Zähringen, and paintings by Holbein, Grun, and other artists. In the centre of the square called the fish-market is a fountain surmounted by a statue of Duke Berthold III. of Zähringen, the founder of the city. The manufactures of the town consist of chicory, chemicals, soap, starch, potash, leather, tobacco, and musical instruments. Freiburg was long the capital of the landgraviate of Breisgau. Pop. (1846) 15,380.
