In honor of National Lighthouse Day, we invited you to share your best lighthouse photos with CNN iReport. As dozens of images started pouring in, we were reminded of a near-universal fact: People love lighthouses. The beacons of light are popular travel destinations across the world.
Here are 10 other lesser-known lighthouse facts:
1. The first lighthouse was Egypt's Pharos of Alexandria, built in the third century BC. The lighthouse of Alexandria was made from a fire on a platform to signal the port entrance.
