Situated in the center of town, the 7 th century Wat Mahathat contains the square-shaped Phra That Phra Anon chedi believed to house the relics of Phra Anon, Buddha's closest disciple. Various festivals are staged here throughout the year.
The highly anticipated annual Rocket Festival is launched at the Phraya Than Public Park. A small stream encircles the 18-rai park with landscaped gardens, children playground and fitness park. The park obtained its name from the Rain God, Phraya Than, who, according to northeastern beliefs, must be presented with shooting rockets to ensure regular rainfall.
After the rice-harvesting season, villagers of Ban Sri Than turn their attention to weaving and producing the famous'mon khit' triangular-shaped pillows, which are hugely popular among visitors.
The village of Ban Toong Nang Oak is noted for its basketry products, and products for common usage such as household utensils and gift items. Fine basketry works and replicas of carved ox-carts can be obtained from the nearby village of Ban Na Samai.
Within Phu Tham Phra (Buddhist Cave Mountain) are numerous sacred, ancient Buddha images housed inside a vast cavern area. It is rather easy to transverse across the simple cavern network, with an entrance at the southern cliff walls and stretching to the north. Explorations are possible at other nearby caves. Because of
the thick foliage, the mountain air is constantly cool and pleasant.
During the summer months of December to May, the receding Chi River exposes a 2-km stretch of sandy beach , transforming it into a recreational area facilitated by food stall establishments.
Historical ruins can be viewed at 2 places in Khum Kuan Kaew District, Wat Song Puey and Dong Muang Tia. The former features an 8-m high Buddha image that is over 200 years old and an ancient chedi that houses soil from a holy place in India. The latter contains ruins of a water pool and the city walls of an ancient town believed to date back to the 7 th century.
Regarded as the prized antique treasure of Yasothon, the Phra Buddha Bath Holy Footprint is located on a white, sandy mound jutting up from the Chi River basin. Nearby is another ancient relic, a laterite Buddha statue in the Nak Prok posture, with ancient scripts inscribed into the laterite slab saying that they were brought over from Ayutthaya in the 8 th century. Also inscribed are prayers paying homage to the Holy Footprint. During March-April, devoted worshippers converge here to pay homage to the Holy Footprint.
Legend has it that historical, laterite Ku Jan pagoda has been in existence since the construction of the famous Phra That Phanom in Nakhon Phanom 1,500 years ago.
The 18 th century, brick Phra That Kong Khao Noi (Small Mound of Rice) pagoda reflects architectural styles of the late Ayutthaya period. Legend says a young farmer built the pagoda as repentance for murdering his mother out of hunger.
