Castle Otttis – Location 29.9559, -81.3063

Castle Otttis, (yes, there are three ‘T’s), was built by Ottis Sadler and Rusty Ickes, between 1984 and 1988. Based on Irish castles from 1000 years ago, it was designed to be a landscape sculpture, open to the elements, and rising up more than 50 feet. Built of split face concrete blocks, reinforced steel rods, poured concrete, cypress and old southern heart pine, the castle weighs an estimated 7 million pounds, and has 88 window openings, left without glass, to allow the weather to flow through it.
The final result is a majestic stone castle built as an expression of artistic and spiritual devotion, along the St Augustine shoreline, recognized by the American Institute of Architects.
Here is the super duper, way challenging, really hard trivia question, which, if solved properly, will lead you to the final coordinates:
