What is the historical significance of the pharos at Alexandria?

The pharos of Alexandria is historically significant because ancient writers included it among the Seven Wonders of the World^[1]. It served as a model for some of the most celebrated lighthouses erected in later times^[1]. The tower was named from the islet on which it stood^[1].

The long narrow island of Pharos lay in front of the city of Alexandria, sheltering both of its harbors^[1]. The famous lighthouse stood on a peninsular rock at the eastern end of the island^[1].
