Very near to the Lazzarettos of Dubrovnik there is a 3D model of the Walls of Dubrovnik and the buildings within it. It shows the Lovrijenac (also known as St. Lawrence Fortress), the Revelin Fortress, the Minceta Tower and so on. The model is white and in the form of a big table. There is also a small three-dimensional compass rose to show the correct orientation. The names of the most important parts are also written on small signs on the table and they also include it in Braille.
