The Venetian Arsenal is a complex of former shipyards and armories clustered together in the city of Venice. Owned by the state, the Arsenal was responsible for the bulk of the Venetian republic's naval power during the centuries. It was one of the earliest large-scale industrial enterprises in history.
Construction of the Arsenal began around 1104, during Venice's republican era. It became the largest industrial complex in Europe before the Industrial Revolution, spanning an area of about 45 hectares, or about fifteen percent of Venice. Surrounded by a 3.2 km rampart, laborers and shipbuilders regularly worked within the Arsenal, building ships that sailed from the city's port. With high walls shielding the Arsenal from public view and guards protecting its perimeter, different areas of the Arsenal each produced a particular prefabricated ship part or other maritime implement, such as munitions, rope, and rigging. These parts could then be assembled into a ship in as little as one day. An exclusive forest owned by the Arsenal navy, in the Montello hills area of Veneto, provided the Arsenal's wood supply.
The Arsenal produced the majority of Venice's maritime trading vessels, which generated much of the city's economic wealth and power, lasting until the fall of the republic to Napoleon's conquest of the area in 1797.
Significant parts of the Arsenal were destroyed under Napoleonic rule, and later rebuilt to enable the Arsenal's present use as a naval base. It is also used as a research center and an exhibition venue during the Venice Biennale, and is home to a historic boat preservation center.References:
The Château Comtal (Count’s Castle) is a medieval castle within the Cité of Carcassonne, the largest city in Europe with its city walls still intact. The Château Comtal has a strong claim to be called a 'Cathar Castle'. When the Catholic Crusader army arrived in 1209 they first attacked Raymond-Roger Trencavel's castrum at Bèziers and then moved on to his main stronghold at Carcassonne.
The castle with rectangular shape is separated from the city by a deep ditch and defended by two barbicans. There are six towers curtain walls.
The castle was restored in 1853 by the architect Eugène Viollet-le-Duc. It was added to the UNESCO list of World Heritage Sites in 1997.
