This diorama presents what the Menorcan shipyards were like during the 19th century. It is a kit by Constructo that I partially modified in its dimensions to adapt it to my preferences.
This model is a recreation of the “ponte girevole” (swinging/revolving bridge) by Leonardo da Vinci. It is a design included in the Atlantic Codex. It is an arched bridge that is supported with a single pillar in one of the banks, after which a counterweight of stones (I used some lead pieces as well as small stones) compensates for the length needed to reach the other shore.
