What are dimensions of the lighthouse of Alexandria?

Answer:
Since it no longer exists we can only rely on descriptions written by people who saw it in use in ancient and medieval times.

The height is estimated at 120 to 140 metres (around 400 to 450 feet) and the tower was about 8.5 metres (28 feet) square, built on a large platform 6.5 metres (21 feet) high.
