Cross-section and plan of the Theodosian Walls of Constantinople
This plate shows a complete cross-section and plan of a typical stretch of the Theodosian Walls. The section shows the different layers of defense. On the plan, are the different shapes of the towers.
From Left to Right:
--Moat ( 61 ft. wide, and more that 20 ft. deep);
--Moat Walls (6 ft. 6 in. high);
--Parateichion (terrace between the outer wall and the moat wall, 61 ft. wide, and it's main purpose was to extend the distance between the besiegers and the besieged);
--The Outer Wall (The outer wall is from 2 ft to 6 ft 6 in. thick, and rises 27 ft, 6 in. above the Parateichion);
--Peribolos (terrace between the Inner and Outer Walls which accommodated the soldiers who defended the Outer Wall. It was 50 to 64 ft. wide.);
--The Inner Wall (96 towers were 57 to 60 ft. high, and spaced between 175 ft. to 181 ft. apart. It rises 40 ft. above the city level and varies in thickness from 15 ft. 6 in. near the base to 13 ft. 6 in. at the top.);
The Theodosian Walls were constructed using both stone and brick. In the detail of the wall showing the cross-section of the wall, both materials can be seen. Brick was used more sparingly than stone.

Side,Top, and Section Views of the trireme "Olympus"
The ship views shown here are scale drawings. The 170 rowers were arranged in three files on each side: 31 in the top bank and 27 in each of the two lower banks. The six files are arranged in a "V" shape, with the lowest bank farthest inboard and the top one farthest outboard. The seats of the rowers in the top and bottom files were angled a few degrees inboard, so that all the oar tips were evenly spaced.

Aleppo Citadel -- Ground Floor Plan -- Entrance Complex
(After Kennedy and Tabaa)
Much remains of Aleppo's medieval defenses, most notably the citadel. Nur al-Din (1147 -74) added an outwork or "fasil" to the city's existing curtain wall to join the already fortified but separate southeast suburb Qal'at al-Sharif to the main city defenses. Nur Al-Din's work also included a second circuit wall or "sur" in advance of the main city wall.

This drawing shows the fortifications and main internal structures in the late 12th to 14th centuries. Saladin's late 12th century fortifications are in black. Early 13th century "great towers" in grey:
1. Upper Enclosure;
2. Lower Enclosure;
3. Bir Yusef well;
4. Mosque of al-Nasir Muhammad;
5. Great Iwan "reception hall of al-Nasir Muhammad";
6. Aqueduct from the Nile;
7. 'Maydon' Training Ground;
9. Burj al-Ramlah tower (After Cresswell, Behrens, and Rabbat).
The Citadel of Cairo has remained a main fortress and military center into the modern times. Consequently most of Sultan al-Adil's buildings within the fortifications were replaced by newer structures during the Mameluke sultanate; then several Mameluke buildings were replaced by those of the Ottoman Turks, most of which were replaced by Muhammad Ali's 19th century reconstruction program. Even today modern additions to the citadel, such as a theatre, are useful for the people of Cairo, but have damaged certain historical remains.

Osberg Ship Plan
Side and Top view of the reconstructed Osberg Ship Plan. Osberg is the oldest Viking ship found, and it and other like it were probably used in the the early Viking raids around the year AD800. It was probably a royal yacht for inshore use. The design is less seaworthy than younger ships. It is supposed by sailing men that the vessel could have made it to Britain during the Summer, but the hull and sailing gear were not nearly as sophisticated as the later ships.
The Osberg ship has oar holes for thirty oars, so we know that this propulsion method was in use some of the time.

Reconstruction of the Ottoman and Venetian Fortress at Butrint (after Karaiska)
During their occupation of Albania in the 15th-16th centuries, the Venetians had constructed a two storey artillery tower with loopholes for cannon at the southwestern corner of an existing 15th century triangular fort. When the Ottomans recaptured the fortress, they quickly installed two further round towers for artillery, in the Turkish style, which had two levels, wooden floors, and four embrasures for smaller cannon at the first floor level.
1. Ottoman (probable) 15th century fortified enclosure;
2. Venetian Artillery tower southwestern corner (square);
3. & 4. Ottoman round towers;
5. Ottoman internal buildings;
6. Venetian outer enclosure;

Ottoman Fortress a Bashtov (after Karaiska)
Most of the construction work done in the 15th and 16th centuries in Albania was military construction because of the warlike actions in that land. One such fortification was the unit built near Bashtov. This fort was a relatively simple design as it was intended to stand on flat ground. The dimensions of the design were approx. 60 x 90 meters, with curtain walls nine meters in height. There were originally seven towers, one at each corner and one in each of three walls. When the fourth wall was destroyed in a later flood the wall was rebuilt and then included the eighth tower. Each of the corner towers were five stories in height and the side wall towers three stories in height. All towers had wooden floors and wooden roofs, and each tower had embrasures for artillery at the ground level. The interior of the curtain walls had false arches and a double row of loopholes. The false arches supported a walkway which gave access to each of the towers. This was never a very important fortress for the Ottomans.
1. Original Ottoman Fort;
2. Western wall destroyed in a river flood and rebuilt;
3. "musalah" (prayer room) above entrance in the main northwestern gate tower.

Vittangi Boat -
Viking ship construction continues today in Scandinavia including production of Viking replicas, small homemade utility vessels, and vessels used by the native Saami such as the one shown above from Vittangi in Northern Sweden. Perhaps someday it will be shown that the design of Viking ships did not originate in the southern Baltic and Europe, but rather from boatbuilding traditions of the northern boreal forests which also survive today.
