Located in Tambon Maha Chai, 200 metres from City Hall. It was constructed in 1828 during the reign of King Rama III because in that period, there was a conflict with the Vietnamese on Chao Anuwong of Vientiane. King Rama III was concerned that the Vietnamese might invade Thailand. Therefore, he commanded Phraya Choduek Ratchasetthi (Thongchin) to be the leader in the construction of a fortress protecting the mouth of the Tha Chin River in Samut Sakhon and called it “Pom Wichian Chodok”. The fortress was made of bricks and cement with no guarding station, but fighting ones, while at the opening in the wall laid the cannons preventing the enemies coming through the mouth of the river.
