A bronze Ottoman cannon from the reign of Selim III, on display at the entrance to the Royal Naval College in the Greenwich district of London.
Weighing 5.5 metric tons, the cannon was cast in 1790–1791. In 1807, following a dispute between the two nations, it was seized from the island of Kınalıada in the Sea of Marmara by the British navy during a landing operation and brought to England. It bears the tuğra of the Ottoman sultan, Selim III, along with the crescent and star symbols.
