This fortress, one of the largest and most impressive in the country, is Coburg's main attraction. The brooding bulk of the castle guards the town from a 1,484-foot hill. Construction began around 1055, but with progressive rebuilding and remodeling today's predominantly late-Gothic–early-Renaissance edifice bears little resemblance to the original crude fortress. One part of the castle harbors the Kunstsammlungen, a grand set of collections including art, with works by Dürer, Cranach, and Hans Holbein, among others; sculpture from the school of the great Tilman Riemenschneider (1460–1531); furniture and textiles; magnificent weapons, armor, and tournament garb spanning four centuries (in the so-called Herzoginbau, or Duchess's Building); carriages and ornate sleighs; and more. The room where Martin Luther lived for six months in 1530 while he observed the goings-on of the Augsburg Diet has an especially dignified atmosphere. The Jagdintarsien-Zimmer (Hunting
Marquetry Room), an elaborately decorated room that dates back to the early 17th century, has some of the finest woodwork in southern Germany. Finally, there's the Carl-Eduard-Bau (Carl-Eduard Building), which contains a valuable antique glass collection, mostly from the baroque age. Inquire at the ticket office for tours.
