The Drassanes at Barcelona is the only example of a medieval naval arsenal in 
		existence that retains much of its original medieval character (Figure 1). All 
		of the others have either been destroyed (Messina, Genoa, Seville, Brindisi, Istanbul), 
		have been remodeled extensively over the centuries (Venice) or had to undergo 
		substantial rebuilding to restore their original form (Valencia). By its very survival, 
		the Drassanes is a truly unique building with no others truly like it in the 
		Mediterranean. For this reason it was declared a Historical and Artistic Monument by 
		the Cabinet of the Spanish Government on 5 May 1976.
        The first date for the Drassanes is hard to place since an open shipyard probably 
		had been in existence since the 12th century. In 1149 the Jews of Tortosa were given 
		the right to build a naval arsenal at Tortosa by Ramon Berenguer IV. The first mention 
		of the Drassanes at Barcelona comes in a document dated September 9, 1243, when James I 
		ordered that no houses or other structures should be built on the beach between "the 
		Ataszana, which is to the West" and the city walls. The Drassanes is again mentioned in 
		another document dated 1255.
		 
		
        The real expansion of the Drassanes began under Pedro III with the start of the War 
		of the Sicilian Vespers (1282-1302) and continued until 1328. The result was a 
		rectangular building of eight covered naus (naves) with a tower at each corner. 
		The walls were fortified and the naves opened on the beach to the East 
		(today Passieg de Josep Carner). Two of the original four towers still exist: the 
		Torre de Mar and the Torre de L'Est. The original 8 naves had openings 8.4 wide and 
		were 8.4 meters high. The naves were approximately 60 meters long and the distance tower 
		to tower across the front and back was approximately 80 meters. This original arsenal 
		covered over 4,800 m2. The typical 108-oared war galley of this time was approximately 
		40 meters in length and approximately 5 meters at maximum beam, which meant the arsenal 
		could hold eight large war galleys. The Google photograph shows 
		the Drassanes from space and the plan of the Arsenal below it is in the same 
		orientation as the photo. The colors on photo correspond to the legend for stages of 
		construction on the plan of the Drassanes. It should be noted that the stages of 
		construction shown are simplified as Drassanes underwent continuous and numerous 
		modifications during its existence.
		 
		
		
        Of course, the arsenal did not just house ships. A letter dated September 4, 1285 
		appointing one Batholomeo Roullant as "custodia" of the "Darassanas" of Barcelona gives 
		a glimpse inside the Arsenal at that time. As the document states, he was responsible 
		for receiving and collecting galleys and all ship in the land with all of their rigging 
		and apparatus and for custody of the same and making to be guarded and procuring in the 
		same arsenal galleys and ships. The Arsenal served as storage for equipment, which was 
		used to arm galleys and ships as necessary. The Arsenal also constructed ships and the 
		heavy rings in the arches used to hoist material and equipment can still be seen today. 
		The Drassanes also produced a great deal of material, both rigging for the ships and 
		arms for the men. As overseer Batholomeo Roullant was paid a salary of 1,000 Barcelona 
		solidi per year. In return he was required to keep his home in the Arsenal. Moreover, 
		he had to provide a yearly accounting of the money he spent on workers' salaries, 
		equipment and material. Though not mentioned, if royal practices were the same in 
		Barcelona as in Sicily at this time, Bartholomeo had at least one notary assigned by the 
		king to keep an accounting.
		 
        Construction continued on the Drassanes up to 1328. It was during this time the city 
		walls were extended to include the Arsenal. The next major construction occurred between 
		1381 and 1390 when the original naves were lengthened. In 1391 work on what was supposed 
		to be a royal residence was started in the northwest corner but in 1401 Martin I decided 
		not to continue it as a residence. The two story structure was finished in 1410 and the low broad semicircular 
		arches leading to the grand stairway form one of the most beautiful parts of the Arsenal. 
		The building is referred to as the New Gallery, but also anachronistically as the 
		Pedro IV Building (Pedro IV died in 1387). In 1489 the Generalitat took control and the 
		building fell into disuse. In 1585 it was used as a billet for troops. However, in 1612 
		the Generalitat decided to enlarge the structure and added three new naves. Following 
		the War of the Reapers (1640-52) the Spanish government further amplified the Drassanes 
		both as an arsenal and a barracks. In 1681 Juan of Austria had another bastion added to 
		the Drassanes fortifications. The last major changes came in the eighteenth century 
		following the War of Spanish Succession (1701-14). In 1725 Phillip V ordered two 
		barracks constructed, one for infantry and one for cavalry (these were torn down in 1935). 
		The last major change which can be seen today was the creation of the Nau Gran 
		(Grand Nave) between 1742-49 by combining the two original central naves. Shortly after 
		this the Drassanes fell out of use as a naval arsenal.
 
		 
		
		In 1802 it was converted into an 
		artillery magazine and by the twentieth century it had fallen into disuse and disrepair. 
		However in 1928 foresighted city officials recognized the historical importance of the 
		structure and intervened. By 1935 they had gotten control of the structure, and in 1936 
		the First Consul of the Generalitat Josep Tarradellas proposed to convert the Drassanes 
		into a maritime museum. The work was delayed by the Spanish Civil War (1936-1939), but 
		in 1940 the three naves by the Torre de la Pau were inaugurated as the 
		Barcelona Maritime Museum (Museu 
		Maritim).  Reconstruction and restoration began in 
		1941, with the main effort between 1951 and 1957. However, work would not be completed 
		until 1966.  The Drassanes today houses one of the great maritime museums and is truly 
		one of the unique historic medieval structures in the world.
