The water castle of Bourtzi is located in the middle of the harbour of Nafplion. The Venetians completed its fortification in 1473 to protect the city from pirates and invaders from the sea. The Greeks regained it from the Turks on June 18, 1822, from where they assisted in the siege of Nafplio. Until 1865 it served as a fortress.
I created the model with Agisoft Photoscan trial using a drone video. Fixes of the geometry and texture map were done in ZBrush.
