Tumladen, the "Valley of Smoothness", was the name for the hidden valley within the Encircling Mountains where the Elven city of Gondolin was built during the First Age.
Turgon, a king of the Noldor, discovered Tumladen under the divine guidance of the Vala Ulmo, Lord of Waters.
- "...Then Tuor and his companion fared over the plain that was of a marvellous level, broken but here and there by boulders round and smooth which lay amid a sward, or by pools in rocky beds. Many fair pathways lay across that plain..."
- ― The Fall of Gondolin
The name comes from the Sindarin elements tum "deep valley" and laden "open, cleared".
