Sri Patani

Phraya Tani (Thai: พญาตานี) or Seri Patani (Malay) is a 17th-century siege cannon from Pattani Province in southern Thailand. It is the largest cannon ever cast in what is now Thailand, measuring 9 feet long and made of brass. It is on display in front of the Ministry of Defence, opposite the Grand Palace in Bangkok. The cannon still serves as the symbol of Pattani Province.
