Part 5/9:
What makes Durin’s Door particularly interesting is its clever concealment; from the outside, it appears as a solid rock face of the mountain until one approaches to utter its magical password. The upper portion of the door showcases a seven-star crown—a nod to Durin’s vision that led to the foundation of Khazad-dûm—while the lower section features a hammer and anvil, symbolizing the artistry of Celebrimbor, echoed alongside two trees that represent the Two Trees of Valinor, hallmark symbols of Elven heritage.
