§ Of Eldamar and the Princes of the Eldalië The Silmarillion

There they dwelt, and if they wished they could see the light of the Trees, and could tread the golden streets of Valmar and the crystal stairs of Tirion upon Túna, the green hill; but most of all they sailed in their swift ships on the waters of the Bay of Elvenhome, or walked in the waves upon the shore with their hair gleaming in the light beyond the hill. Many jewels the Noldor gave them, opals and diamonds and pale crystals, which they strewed upon the shores and scattered in the pools; marvellous were the beaches of Elendë in those days. And many pearls they won for themselves from the sea, and their halls were of pearl, and of pearl were the mansions of Olwë at Alqualondë, the Haven of the Swans, lit with many lamps. For that was their city, and the haven of their ships; and those were made in the likeness of swans, with beaks of gold and eyes of gold and jet. The gate of that harbour was an arch of living rock sea-carved; and it lay upon the confines of Eldamar, north of the Calacirya, where the light of the stars was bright and clear.
