The above is the view of the entrance to the Arsenal.
To understand the glorious past of Venice, you must be familiar with Venetian Arsenal. The Arsenal is a former shipyard where Venetian ships were built. Being the center of Venetian Naval industry from the 13th century, it was the largest industrial complex in Europe before the Industrial Revolution. The Arsenal producing many vessels generated great wealth and power for Venice until 1797 when Napoleon took over the area.
Before 1200, Venetian ships were built in small shops scattered throughout the city. Shortly after 1200, these small businesses were organized and grouped into one single large shipyard - the Arsenal.
The high walls prevents public from seeing what is inside the complex.
The Byzantine-style building already existed by the early 13th century. This main gate was built around 1460. The two lions sitting on the left and right of the door were taken from Greece.
The winged lion, the Lion of Venice, is above the door.
