King Taksin’s royal palace to open for free visits in December

BANGKOK – History enthusiasts and visitors interested in Thailand’s royal heritage will have a rare opportunity to explore the historic Thonburi Palace, also known as Wang Derm Palace, free of charge for eight days from 21 to 28 December 2026.

The former royal residence of King Taksin the Great, located within the Royal Thai Navy headquarters beside Wat Arun on the banks of the Chao Phraya River, will open to the public to commemorate the 259th anniversary of the establishment of Thonburi as Thailand’s capital.

Visitors will be able to explore several historic buildings within the palace grounds, including the Throne Hall, the Twin Chinese-style Residences, King Pinklao’s Residence and the Whale Head Shrine.

The palace will be open daily from 09.00 to 15.30, with free admission and no entry pass required.

Visitors can enter through two access points: the main entrance to the Royal Thai Navy headquarters and the side entrance next to the wall of Wat Arun.

The special opening will also allow visitors to pay their respects at the monument to King Taksin the Great, who established Thonburi as the capital in 1767.

A palace steeped in Thai history

Thonburi Palace was built in 1767 on the orders of King Taksin following his restoration of Thai independence. It served as both his royal residence and administrative centre during the Thonburi period.

Situated near the mouth of Bangkok Yai Canal, the palace occupies a strategically important position along the Chao Phraya River, providing access to major waterways and military routes.

The site was previously associated with Wichai Prasit Fort, which dates back to the reign of King Narai.

Today, the historic palace stands within the Royal Thai Navy headquarters on Wang Derm Road in Bangkok Yai district, preserving architectural and historical landmarks from Thailand’s former capital.

The eight-day opening offers both Thai and international visitors an opportunity to discover a significant chapter of Thai history and explore a royal palace that is not normally freely accessible to the general public.
