Phitsanulok Mansion

Phitsanulok Mansion, originally named Baan Banchini, was commissioned in 1922 by King Rama VI (King Vajiravudh) as a royal gift for his trusted aide-de-camp and close confidant, Phraya Anirutdecha (M.R. Thum Sanidvongs). The palace was designed by the renowned Italian architect Mario Tamagno—who also designed Bangkok's Ananta Samakhom Throne Hall and Hua Lamphong Railway Station—in an opulent Venetian Gothic revival style featuring marble statues, sweeping staircases, and sprawling landscaped gardens.

Following the 1932 Siamese Revolution which transitioned Thailand into a constitutional monarchy, the Anirutdecha family offered the estate to the Royal Thai Government. During World War II, the mansion served as the state guest house for visiting Japanese dignitaries and military commanders. In 1979, Prime Minister General Kriangsak Chamanan sponsored an extensive multi-million baht restoration, officially designating Baan Phitsanulok as the executive residence for the Prime Minister of Thailand.

Despite its lavish luxury and state designation, the mansion earned an extraordinary political reputation: nearly all of Thailand's modern Prime Ministers—throughout the late 20th and early 21st centuries—refused to reside in the master bedroom, using the estate exclusively for daytime state receptions, cabinet meetings, and diplomatic galas before returning to their private residences to sleep.

The supernatural reputation of Phitsanulok Mansion centers on the belief that the palace grounds are zealously guarded by ancient royal spirits and tutelary deities who react aggressively to any occupant who lacks sufficient spiritual purity or respect. The primary legend tells of a colossal bronze statue of Roman god Mercury (commonly called 'Phra Narai' or the Winged Messenger) standing in the central courtyard garden, which is believed to host a powerful ancestral guardian spirit protecting the Dusit royal estate from corrupt intrusion and improper conduct.

According to political lore and royal staff accounts, Prime Minister General Prem Tinsulanonda attempted to move into the executive suite in 1981. On his very first night, he was reportedly awoken at 2:00 AM by the sound of heavy galloping horse hooves echoing across the marble hallways outside his bedroom door. Upon opening the door, he encountered an imposing phantom warrior clad in ancient Thai armor who warned him that no politician was permitted to sleep above the estate's true spirit masters. General Prem fled the building before dawn and never slept in the mansion again throughout his entire eight-year term in office.

Another widely circulated story claims that staff members who failed to pay proper homage at the spirit shrine before commencing maintenance work suffered sudden illnesses, terrifying nightmares of drowning, or saw marble statues in the hallway moving their eyes to track human movements.

Security personnel, military guards, and government staff assigned to Phitsanulok Mansion report a wide array of intense, consistent paranormal phenomena. Security guards patrolling the perimeter late at night report hearing the clear sound of classical piano music playing softly from empty, locked ballrooms where all electrical power has been shut off for the night.

Multiple nightwatchmen have documented seeing the apparition of a high-ranking noblewoman in early 20th-century Thai court dress strolling through the manicured gardens near the Roman courtyard pool at midnight, vanishing into thin air when approached by security personnel. This spectral figure is believed to be a former royal resident of the estate watching over the property.

Other reported phenomena include sudden, drastic temperature drops in the grand dining hall during summer months, electronic security sensors and motion alarms triggering spontaneously in empty locked rooms, and the persistent sound of heavy boots marching across the second-floor wooden balconies when no personnel are present.

Phitsanulok Mansion is considered one of Thailand's premier architectural masterpieces of Venetian Gothic revival style. The main two-story mansion features a striking pale pink and cream exterior facade adorned with pointed arch windows, marble balconies, and ornate stucco carvings.

The interior boasts a grand central staircase crafted from imported Italian marble, high vaulted ceilings adorned with gilded plasterwork, crystal chandeliers, executive conference rooms, state banqueting rooms, private presidential suites, and expansive reception halls. The surrounding 50-rai estate includes a bronze fountain plaza, private security quarters, guest pavilions, and lush tropical gardens, representing a magnificent blend of European architecture and Thai royal heritage.

Phitsanulok Mansion is an active state property and official executive residence, located on Phitsanulok Road in the Dusit district of Bangkok. The mansion is strictly closed to the general public and casual tourists, guarded 24/7 by armed military and police security.

Tourists and architecture enthusiasts can view the grand exterior gates, perimeter walls, and upper gables of the mansion from the public sidewalk along Phitsanulok Road. Photography of the exterior from public roadways is permitted, though approaching security gates or attempting unauthorized entry is strictly prohibited. Viewing the building from nearby Dusit palace streets offers an enjoyable historical tour experience.

Phitsanulok Mansion's reputation as Thailand's most haunted official building is legendary because it is acknowledged by the highest levels of Thai government. The fact that successive Prime Ministers officially avoid sleeping inside the executive suite provides unique real-world validation to a century of royal ghost lore, historical intrigue, political tradition, and architectural grandeur across Southeast Asia, cementing its iconic status.
