Abandoned Houses in Gulf Shores

I am interested in abandoned houses, but I do not usually think of finding them at the beach. Actually, these 2 have been abandoned for some time as I remember seeing them in the past. They appear to be in danger of being gobbled up by the high rise which is sneaking up on them from the rear. Both of these houses were/are beautiful and I am especially attracted to the Spanish style one and the lovely gates. I wonder what sad story is behind these 2 houses.
