Prior to its settlement by the Elves, Tumladen was a great lake, which was eventually drained by the Dry River. It was located east of the upper waters of Sirion, as was found out later by the Elves, in the middle of the Encircling Mountains. Turgon was shown by Ulmo, a Vala, where it was located by means of a dark tunnel that ran deep under the mountains, hollowed out by streams that ran to join the Sirion. In this way, Turgon discovered the vale of Tumladen, and thought it indeed to be a perfect place to construct his city that was supposed to be modeled after the great city of Tirion upon the green hill Tuna, back in Valinor. Indeed, after many years of labor, Gondolin did come to rival Tirion with its beauty and splendor. Gondolin, the city contained within Tumladen, survived for more than 503 years, the longest-lived of the Ñoldorin kingdoms. The vale was eventually betrayed by Maeglin, however, and in so doing, Maeglin brought about the destruciton of the last kingdom of the Ñoldor in Beleriand. It was there that the battle of Ecthelion of the Fountain and Gothmog, the Lord of Balrogs, took place in the very square of the King. There it was also that they slew each other, and in so doing, Ecthelion felled the mightiest of Balrogs, even though he himself was slain. And so, with the treachery of Maeglin, the fair vale of Tumladen and the city of Gondolin were destroyed and ruined.
Tumladen is a name coming from two Sindarin roots. One of the roots is tum (pronounced toom), which means a valley. The other Sindarin root is lad, which means a plain or a valley. Both parts of this name doubly imply and tell that Tumladen is a plain/valley, a very interesting combination of Sindarin roots on the part of Tolkien.
