This is the Biloxi Lighthouse in Biloxi, Mississippi. Built in 1848, It was one of the few structures still standing along the Mississippi coast after hurricane Katrina passed through. There is still substantial devastation in and around Biloxi. A few casinos have rebuilt, but little else. We were glad to see the lighthouse still there when we visited the area last week.
This is the infrared version. I posted a duotone version below.
