Its name meaning "Elephant Pier" ("Tha" is jetty, pier and "Chang" is elephant), it was built in the reign of King Phutthayotfa Chulalok (Rama I), who was the first monarch of Chakri Dynasty and the founder of Rattanakosin Kingdom. At that time, elephants from the Grand Palace were brought to this area to take a bath, therefore making it called "Tha Chang" in Thai.

It was formerly a royal pier and then a ferry port, taking passenger to Bangkok Noi railway station and other places along the canal Khlong Bangkok Noi.

The pier where royal elephants were brought for bathing known as "Tha Chang Wang Na" (The Front Palace's Elephant Pier). In the King Rama IV's reign, Prince Pinklao (second king resided at front palace) preferred his courtiers to park their barges at the pier near to his residence. He ordered to demolish part of the city wall and replaced by a gate for the royal elephant passing by. The pier was called Tha Chang since then.
