8 Best Sights in Around Bangkok, Thailand

Building began on this royal monastery in 1374 and was completed during the reign of King Ramesuan (1388–95). The tree-shaded, spacious, and parklike grounds, a pleasant place to linger, contain what's left of the monastery's 140-foot prang. The brick Khmer-style prang—which collapsed twice between 1610 and 1628, and again in the early 20th century—barely reflects its former glory. Partially in ruins, the prang is said to contain relics of the Lord Buddha. It and the beheaded Buddhas that remain in Wat Phra Mahathat are a result of the Burmese sacking of the temple in 1767.

This 800-year-old Khmer-influenced structure on the western side of the Phetchaburi River is a royal monastery located in a charming district with narrow lanes and wooden shophouses. It comprises five large prangs (Khmer-style towers) that are visible from all over town. It is notable for its fine stucco work, which is characteristic of the Phetchaburi school of art seen in many of its temples.

On a small island in the Chao Phraya River within the grounds of the Bang Pa-In Royal Palace stands an enchanting retreat that is considered the only European-style Buddhist monastery in Thailand. A large French-made stained-glass panel high above the entrance to the hall bears an image of King Chulalongkorn, who had the temple built in 1876 in order to perform religious practices during his stay at Bang Pa-In Palace. The most impressive structure in the compound is the ordination hall, built in a strikingly English Gothic style with its elongated steep spire and its arched windows and doorways. Brick paths and stone buildings with arched windows suggest a Gothic abbey. The peak of the diamond-patterned tile roof is laid with impressive Victorian iron grillwork, while the steeple is topped by an iron weathervane.

This bustling temple complex on the banks of the Lopburi River is an interesting diversion from the dormant ruins that dominate Ayutthaya. A short B4 ferry ride across the river sets the scene for its dramatic origins. The temple was built in 1324 (26 years before Ayutthaya's rise to power) by a U-Thong king in atonement for the death of his fiancée. Instead of bringing his bride, a Chinese princess, into the city himself, the king arranged an escort for her. Distraught at what she interpreted to be a lackluster welcome, the princess threw herself into the river (at the site of the current temple) and drowned. Inside the main chapel sits a highly revered, gilded 19-meter-high seated Buddha dating to 1334.

Built on a Hindu religious site originally established by the Khmers in the 11th or 12th century, this wat underwent so many restorations during the Sukhothai and Ayutthaya periods that it's difficult to discern the three original Khmer prangs—only the central one is intact. Several Sukhothai- and Ayutthaya-style chedis sit within the compound.

The royal family worshipped at this wat, Ayutthaya's largest temple. The 14th-century structure lost its 50-foot Buddha in 1767, when the invading Burmese melted it down for its 374 pounds of gold. The trio of chedis survived and are the best existing examples of Ayutthaya architecture; enshrining the ashes of several kings, they stand as eternal memories of a golden age. If the design looks familiar, it's because Wat Phra Si Sanphet was the model for Wat Phra Kaew at the Grand Palace in Bangkok. Beyond the monuments you can find a grassy field where the Royal Palace once stood. The foundation is all that remains of the palace that was home to 33 kings.

Across from Wat Phra Mahathat stands Wat Ratchaburana, whose Khmer-style prang dominates the skyline. Original carved stucco statues of mythical creatures and lotus flowers can still be seen on the main prang, which is surrounded by four Sri Lankan–style stupas. King Borommaracha II (Chao Sam Phraya) built this temple in 1424 to commemorate the death of his two older brothers, whose duel for the throne ironically left him as king. Their relics, including their swords, were buried in a crypt under the prang's base, which was looted in 1957. Arrests were made, however, and the retrieved treasures can now be seen in the Chao Sam Phraya National Museum.

King Naresuan constructed the enormous chedi at Wat Yai Chai Mongkol, the largest in Ayutthaya, after defeating the Burmese crown prince during a battle atop elephants in 1593. A painting of the battle is one of the temple's highlights. The complex, parts of which date to 1357, was totally restored in 1982. Linger a while to pay your respects to the huge reclining Buddha, or climb to the top for a spectacular view. The site closes at 5 pm, but you can enter after that if the gates are left open, as they often are. The view at sunset is beautiful, and you'll completely escape the crowds.
