Who was Otto Hillig?
Depending on who you ask: a photographer, pilot, castle builder, adventurer... or the man who hid N**i treasure somewhere in the Catskills.
Born in Germany, Hillig spent decades documenting Sullivan County, creating an archive of over 60,000 aerial photographs and 50,000 glass plate negatives.
In June 1931, Hillig and Danish pilot Holger Hoiriis took off from the 9th fairway of what is now the Sullivan County Golf & Country Club aboard The Liberty, making international headlines with their transatlantic flight to Europe.
He later built the stone castle that still overlooks Liberty and according to local legend, hid a cache of N**i treasure somewhere on the property, leaving behind clues that treasure hunters chased for decades.
More than 70 years after his death, Otto Hillig remains one of the Catskillsā most fascinating and mysterious characters.
Join us following our Ferndale Historic Marker Dedication this Sunday, June 28 from 5ā7 PM at Ottoās, the restaurant named in Hilligās honor at the Sullivan County Golf & Country Club, where his flight once began.
This special one-night celebration of Ferndaleās Borscht Belt history will feature rare photographs, storytelling, music, a Marker Project merch pop-up, and specialty cocktails and food available for purchase. ā¤ļø
