Olwë, King of the Falmari, lived in Alqualondë. The city is said to be north and east of Tirion between the Calacirya and Araman in northern Eldamar. It is perhaps best known as the site of the First Kinslaying recounted in The Silmarillion.
The city was built in a natural harbour made of rock, and was also walled. Other than the great harbours it also housed the Tower of Olwë. The city was covered with the pearls the Elves had found in the sea and jewels which they obtained from the Noldor. The famed swanships were moored here.
