Introduction to Wat Arun: Wat Arun (Wat Arun) is located on the west bank of the Chao Phraya River. It is one of the royal temples in Thailand and is commonly known as Wat Arun. Built in the Ayutthaya Dynasty, it is a temple to commemorate Thailand's 41st king and national hero Zheng Zhao. It is huge in size, second only to the Grand Palace and the Temple of the Emerald Buddha. The main pagoda temple now houses the statue of King Zheng Zhao and his relics, and there are Chinese-style lanterns hanging in the hall. There is a giant stone statue of the patron saint at the entrance of the temple. There are five identical pagodas in the temple, one big and four small. The big tower is a 79-meter-high Brahmin-style minaret - Bajrang Pagoda. It was built in 1809 and is known as "Thailand's Eiffel Tower". There are stairs inside the tower for tourists to climb. From the tower, you can have a panoramic view of Bangkok on the other side of the Chao Phraya River. Cityscape.
