Parece que Tolkien falou pouco sobre a estrutura de Gondolin. De fato, de acordo com

For the fashion of Minas Tirith was such that it was built on seven levels, each delved into the hill, and about each was set a wall, and in each was a gate. But the gates were not set in a line: the Great Gate in the City wall was at the east point of the circuit, but the next faced half south, and the third half north, and so to and fro upwards; so the paved way that climbed toward the citadel turned this way and that and then that across the face of the hill.
