The bombardments during World War II brought great destruction to the castle. The main donjon was fortunately fully reconstructed. Reconstruction of the Honmaru Palace begun in 2009 and is expected to be completed by 2017. The Nagoya castle is recognised for its golden dolphins on the castle’s topmost roof. Each of them (male and female) contain approximately 45 kg of gold. The keep is the main attraction at Nagoya Castle with fully modern facilities and exhibits relating to the castle’s history. The panorama of Nagoya from the upper level observatory is also quite impressive.
