The original shed, built in 1908-09 and first used in 1910, is now the ring building factory, where the great transverse frames for the Zeppelins are made. It is 603½ feet (184 meters) long, 150.8 feet (46 meters) wide and stands 65.6 feet (20 meters) high—huge dimensions in the early days but utterly dwarfed by the great sheds which have since appeared alongside. There are double doors at each end, one set operated on the turning, the other on the sliding principle. They are opened and closed by electricity in a few minutes. In this shed twenty-eight Zeppelins were assembled, the last being LZ-39 after which it was devoted to the transverse ring frames. [PLATE 31: The “DELAG” Passenger Zeppelin “Victoria Louise”, 1912. The “DELAG” Passenger Zeppelin “Victoria Louise”, 1912.] Twenty Zeppelins were built in the new shed, number one (Plate 16), which is 629.8 feet (192 meters) long, 129.23 feet (39.4 meters) wide and 91.8 feet (28 meters) high. Its double sliding doors are electrically operated. Six of the larger Zeppelins were either built or reconstructed in another new shed, number two, erected to accommodate ships of 1,942,050 cubic feet (55,000 cubic meters) and more. It is 787.2 feet (240 meters) long, 150.8 feet (46 meters) wide and 114.8 feet (35 meters) high. Its sliding doors can be opened or closed within fifteen minutes. Both of the large sheds have long docking rails at each end which enables the Zeppelins to leave or return to shelter within a few minutes. Another shed near the works at Loewental was turned over to Zeppelin by the Government. The Navy Zeppelin L-11 was built there in 1915. The last one was the navy ship L-72 which was completed as the armistice was signed. It was not inflated for delivery; and, therefore, remained the property of the Zeppelin Company. In the spring of 1919 the L-72 was outfitted for a demonstration flight from Berlin to the United States and return; but it was prevented by the Allied Commissions which ordered it to be kept in the shed until delivered to France. All the Zeppelins assembled at Loewental were fabricated at the main plant and taken there only for final assembling of the parts.
