Freiburg Minster is the cathedral of Freiburg im Breisgau, southwest Germany. The last duke of Zähringen had started the building around 1200 in romanesque style. The construction continued in 1230 in Gothic style. It has a beautiful interior with many works of art, including 14th-century stained glass in the aisles, a famous altarpiece dating from 1512, and an altarpiece in the University Chapel by Hans Holbein the Younger from 1521. From the platform of the delicately articulated 116-meter-high tower, built in 1330, you'll be rewarded with magnificent views of the old city.
