A casemate is a fortified gun emplacement or armoured structure from which guns are fired, in a fortification, warship, or armoured fighting vehicle.
When referring to antiquity, the term "casemate wall" means a double city wall with the space between the walls separated into chambers, which could be filled up to better withstand battering rams in case of siege (see § Antiquity: casemate wall.)
Panzerkampfwagen VIII Maus (English: 'mouse') was a German World War II super-heavy tank completed in July of 1944. As of 2025, it is the heaviest fully enclosed armored fighting vehicle ever built. Five were ordered, but only two hulls and one turret were completed; the turret being attached before the testing grounds were captured by the Soviet military.
These two prototypes underwent trials in late 1944. The complete vehicle was 10.2 m (33 ft) long, 3.71 m (12.2 ft) wide and 3.63 m (11.9 ft) high. Weighing about 188 metric tons, the Maus's main armament was the Krupp-designed 128 mm KwK 44 L/55 gun, based on the 12.8 cm Pak 44 towed anti-tank gun also used in the casemate-type Jagdtiger tank destroyer, with a coaxial 75 mm KwK 44 L/36.5 gun. The 128 mm gun was powerful enough to destroy all Allied armored fighting vehicles in service at the time, with some at ranges exceeding 3,500 m (3,800 yd).
The Bock (Luxembourgish: Bockfiels) is a promontory in the north-eastern corner of Luxembourg City's old historical district. It was here that Count Siegfried built his Castle of Lucilinburhuc in 963, providing a basis for the development of the town that became Luxembourg. Over the centuries, the Bock and the surrounding defenses were reinforced, attacked, and rebuilt time and time again. as the armies of the Burgundians, Habsburgs, Spaniards, Prussians, and French vied for victory over one of Europe's most strategic strongholds, the Fortress of Luxembourg. Warring did not stop until the Treaty of London was signed in 1867, calling for the demolition of the fortifications. Ruins of the old castle and the vast underground system of passages and galleries known as the casemates continue to be a major tourist attraction.
Jonathan Williams (May 20, 1750 – May 16, 1815) was an American military officer, engineer, and politician. He served as the first superintendent of the United States Military Academy from 1801 to 1803 and from 1805 to 1812. He served as chief of engineers of the United States Army Corps of Engineers from 1802 to 1803 and from 1805 to 1812. He led the construction of fortifications in New York Harbor from 1807 to 1811, including Castle Williams, the first casemated battery in the United States. He served as a member of the United States House of Representatives for Pennsylvania in 1815 but died before the 14th United States Congress assembled.
The Stepped Stone Structure is the name given to the remains at a particular archaeological site (sometimes termed Area G) on the eastern side of the City of David, the oldest part of Jerusalem. The curved, 60-foot-high (18 m), narrow stone structure is built over a series of terraces (hence the name). A casemate wall adjoins the structure from a northerly direction at the upper levels, and may have been the original city wall.
The Munot is a circular 16th-century fortification located on Emmersberg hill in the city of Schaffhausen, Switzerland, and serves as a symbol of the city. It is surrounded by vineyards, which have been cultivated since the early 20th century. The structure was built between 1564 and 1589, partly through compulsory labor (Frondienst), and formed part of the city’s defensive fortifications. The site had earlier fortifications, with references to a structure called Annot in 1376 and Unot in 1460.
The Munot's circular design strongly reflects the fortress concepts of Albrecht Dürer. Its lower level consists of a hexagonal trench structure with caponiers (defensive turrets), above which are circular casemates and a battlement platform. A projecting tower on the city-facing side rises to a height of around 50 metres.
