Wat Suwandararam is located on the city island near the Pom Phet fortress. There are two entrances along U-Thong Road leading to this active monastery. During the Ayutthaya period, this area had a thriving community of Chinese traders. It was full of warehouses for maritime markets, and foreign boats were required to dock in the nearby harbor. A canal wrapped around Wat Suwandararam, which led to the Pom Phet and Pom Hor Rajakuk fortresses. There monastery may be pictured in several maps by foreigners. The 1660 Dutch map by Vingboons clearly show a temple at this location. The 1751 map by de La Mare lists a Chinese pagoda in the area. These may have been precursors to the construction of Wat Suwandararam.
