In Turkish, Uludağ means "Sublime Mountain", but in colloquial Turkish, the older name Keşiş Dağı, "Mountain of Monks," is still used. In ancient times the range of which it is a part, extending along the southern edge of Bithynia, was known as Olympos in Greek and Olympus in Latin, the western extremity being known as the Mysian Olympus and the eastern as the Bithynian Olympus, and the city of Bursa was known as Prusa ad Olympum from its position near the mountain. Throughout the Middle Ages, it contained hermitages and monasteries: "The rise of this monastic centre in the 8th c. and its prestige up to the 11th are linked to the resistance of numerous monks to the policy of the iconoclast emperors and then to a latent opposition to the urban, Constantinopolitan monasticism of the Studites.". One of the greatest monks of the Christian East, the wonder-working Byzantine monk Saint Joannicius the Great, lived as a hermit on this mountain.
Mt. Uludağ is the highest mountain of the Marmara region. Its highest peak is Kartaltepe at 2,543 m (8,343 ft). To the north are high plateaus: Sarıalan, Kirazlıyayla, Kadıyayla, and Sobra.
There is an abandoned wolfram mine near the summit. The mine and the integrated plant, which were built in 1974 for 60 million dollars, were eventually closed in 1989 due to high production costs.
The highest area in western Anatolia, Uludağ is easily ascended by car or cable-car. The park is about 22 km (14 mi) south of Bursa and is signposted from there. Bursa can be reached by road from Istanbul. The cable-car ascends from Bursa and has an intermediate stop in the alpine meadows of Kadiyayla at about 1,200 m (3,937 ft) elevation. It ends at Sarialan at about 1,630 m (5,348 ft).
