And the Horton Point Lighthouse Contest Winner is...

The Southold Historical Society is happy to announce the winner of the Horton Point Lighthouse Anniversary Photo Contest. The contest received over 100 entries during July and August of 2017. A selected jury reviewed all entries and awarded the winner. The winning photograph was submitted by Sean P. Mills and shows a beautiful landscape of Horton Point Lighthouse. Mr. Mills is a passionate photographer who spends the year pursuing the Sun, the Moon, and the seasons all along the length of Long Island. You can see his work on Facebook under Sean P. Mills Photography. We celebrate the enthusiasm of our visitors to the Horton Point Lighthouse this summer and thank all the photographers that submitted photos to the contest. The Horton Point Lighthouse is open for visitors every Saturday and Sunday from 11:30 AM to 4:00 PM until Columbus Day Weekend.
