Nidzica castle construction was begun around 1370. The Pfleger of the Teutonic Knights made it his residence in 1409. On 12t July 1410, the undefended castle was captured by the Polish forces on their way into the interior of the State of the Teutonic Order. At the time of the Hunger War of 1414 the castle was put under siege by the Polish knights and taken after eight days on the 6th of July. In 1454 the castle was occupied by the Prussian Union and in February 1455 was taken by the Czech army led by Jan Kolda ze Zampachu, who had repulsed an attack an by the forces of the Teutonic Knights on 28 April.
In 1517 the inner ward was built up and reinforced. In 1784 a fire consumed the innter ward. In 1812 the castle was devastated by French forces. The castle was rebuilt from 1828-1830 into a court and a prison. The Soviet army bombarded the castle in 1945 and it remained in ruins until its rebuilding in 1961-1965.References:
The Baths of Caracalla were the second largest Roman public baths, or thermae, in Rome. It was built between AD 212 and 217, during the reigns of Septimius Severus and Caracalla. They would have had to install over 2,000t of material every day for six years in order to complete it in this time.
The baths remained in use until the 6th century when the complex was taken by the Ostrogoths during the Gothic War, at which time the hydraulic installations were destroyed. The bath was free and open to the public. The earthquake of 847 destroyed much of the building, along with many other Roman structures.
The building was heated by a hypocaust, a system of burning coal and wood underneath the ground to heat water provided by a dedicated aqueduct. It was in use up to the 19th century. The Aqua Antoniniana aqueduct, a branch of the earlier Aqua Marcia, by Caracalla was specifically built to serve the baths. It was most likely reconstructed by Garbrecht and Manderscheid to its current place.
In the 19th and early 20th century, the design of the baths was used as the inspiration for several modern structures, including St George's Hall in Liverpool and the original Pennsylvania Station in New York City. At the 1960 Summer Olympics, the venue hosted the gymnastics events.
