Religious architecture in Hoi An is relatively ornate as compared to other kinds of architecture. It is scattered throughout the town and surrounding areas. One example of religious architecture is the Phuoc Lam Pagoda, located in Cam Ha village, about 3 kilometers from Hoi An. Built in the eighteenth century by the Buddhist monk Minh Giac, it still has many valuable statues, relics, canons and steles that illustrate the important role Hoi An had in integrating and developing Buddhism in Southern Viet Nam.
Scattered about the countryside around Hoi An are three Japanese tombs dating from the 17th century. Although not elaborately constructed, they are of great historical significance since they are the only tombs of Edo-era Japanese merchants known outside of Japan proper. These tombs are convincing evidence of foreigners coming to Hoi An to establish trading businesses in the past centuries.
Ancient wells can be found in many locations in and around Hoi An. Most wells were built of bricks to help filter the water. The oldest well found to date was dug by the Cham people, in a square shape. An example of Cham-specific well is located at Cam Ha village; it has a diameter of 1 meter and stone walls about 10 centimeters thick. Moreover, it is surrounded by four stone columns and a small rectangular yard.
