Castle Otttis was created as an original landscape-sculpture...
”Done in Remembrance of JESUS CHRIST.” A landscape-sculpture is defined as a structure built to adorn or to view the landscape.
Castle Otttis is an impression of an Irish castle of 1,000 years ago. The interior was created under guidance of historians
from the Catholic Diocese of Northeast Florida to evoke an
atmosphere of an Abbey (or early Christian church) in Ireland during the same period.
