Lighthouses are throwbacks to a time without GPS, when they served as crucial beacons on dark nights. And today's their day.

It's National Lighthouse Day, and the folks at the Hereford Inlet Lighthouse in North Wildwood (111 N. Central Avenue) invite you to celebrate the creation of the U.S. Lifesaving Service 228 years ago. 

Until 4 p.m. today, enjoy guest speakers -- including former lighthouse keepers and historians -- food, and author and artist signings. Admission is free.

The Hereford Inlet Lighthouse began operating in 1874, and its 50 foot tower with a beacon that extends for 13 nautical miles continues as a navigation aid today. The building was moved 150 feet to the west of its original location near the water after waves from a 1913 nor'easter undermined its foundation. 

The site is known for its residential style building and well-maintained gardens.
