Construction of Azuchi Castle — Chief Director of the Grand Castle Project Embodying Nobunaga's Vision
Niwa Nagahide served as chief director of the construction of Azuchi Castle, which began in 1576. He brought to reality Nobunaga's grand vision of building on Mount Azuchi by Lake Biwa a massive castle complex featuring a tenshu (main tower) of a scale without precedent. Azuchi Castle was completed in 1579 and served as a symbol of Nobunaga's political and cultural authority—but was destroyed by fire immediately after the Honnoji Incident of 1582. Nagahide was known by the nickname 'Kome-Gorozae' and was celebrated for his integrity; he was valued by both Nobunaga and Hideyoshi. The site of Azuchi Castle remains in Omihachimanshi, Shiga, designated as a National Special Historic Site.
