You may think lighthouses where not in medieval times but they where! just read my creation description...
About this creation
Tang Dynasty Chinese writer Jia Dan wrote in his book (written between 785 - 805) that in the sea route forming the opening mouth of the Persian Gulf, the medieval Iranians had erected large minaret towers that served as lighthouses. Confirming the Chinese reports, a century later, Arab writers al-Mas'udi and al-Muqaddasi wrote of the same lighthouses.
One of the oldest working lighthouses in Europe is located at Hook Head in County Wexford, Ireland. It was built during the medieval period, in a sturdy circular design
Ok so now you know that you should know that this was built in LDD.
I used a circular design for the tower but getting stairs inside the tower was a pain...
so here are some pictures...
