Wat Ratchanatdaram, located in Bangkok's historic Phra Nakhon district, is one of the must-see places in Bangkok for travelers who appreciate architecture, spirituality, and history intertwined. Commissioned in 1846 by King Rama III for his granddaughter, Princess Somanass Waddhanawathy, this temple stands out for its striking design and unique structure-Loha Prasat, the “iron castle.” With its 37 spires gleaming under the tropical sun, it symbolizes the 37 virtues of enlightenment in Buddhist philosophy.

This spot is one of the best places to see in Bangkok if you're exploring Rattanakosin Island, not only for its distinctive appearance but also for its serene ambiance. Unlike the crowded temples nearby, Wat Ratchanatdaram offers quiet corners, graceful symmetry, and one of the best rooftop views of the Old City skyline-a great place to visit on a walking tour of Bangkok.

History and Significance of Wat Ratchanatdaram

Wat Ratchanatdaram, which translates to “Temple of the Royal Niece,” was established in 1846 under King Nangklao (Rama III). It was part of his broader vision to expand and beautify Bangkok with monumental religious architecture. The temple was constructed to honor his beloved granddaughter, Princess Somanass Waddhanawathy, who tragically died young.

The temple’s architectural centerpiece, Loha Prasat, takes its inspiration from ancient Buddhist structures once found in India and Sri Lanka. The original Loha Prasat in Sri Lanka was built in Anuradhapura and featured multiple tiers and thousands of rooms, though none of those earlier examples survive today. Bangkok’s version, standing 36 meters tall, is the only one remaining in existence.

Its pyramid-like design is formed by a square base that narrows toward a central spire, embodying Buddhist cosmology. The 37 metal-tipped spires represent the Bodhipakkhiya Dhamma-the qualities required to achieve enlightenment. Loha Prasat’s structure is also a tribute to King Rama III’s fascination with architectural forms that blended Thai, Sri Lankan, and Burmese styles, reflecting the spiritual and cultural connections between these Buddhist nations.

In 2005, Wat Ratchanatdaram’s Loha Prasat was nominated for inclusion in the UNESCO World Heritage list, further cementing its importance as a cultural and historical treasure.

Things to See and Do in Wat Ratchanatdaram

The main attraction here is, without question, Loha Prasat-the iron castle. Visitors can climb its multiple levels, each offering a new perspective on the temple’s geometric perfection. The labyrinth of corridors on the ground floor is lined with columns and tranquil meditation spaces, while the upper levels provide views of Bangkok’s rooftops and the nearby Golden Mount (Wat Saket).

Inside, you’ll find exhibits detailing the history of Loha Prasat, including photographs, architectural models, and murals added in 2007 that illustrate its construction and symbolic meaning. The topmost level houses a relic of the Buddha, making it a sacred pilgrimage spot for Thai Buddhists.

Surrounding the main structure are smaller pavilions, prayer halls, and a courtyard filled with serene statues. The temple complex is beautifully illuminated in the late afternoon, when the sunlight reflects off the black iron spires and golden tips. For a peaceful end to your visit, stroll over to the nearby Mahakan Fort or enjoy a drink at one of the riverside cafés just a short walk away.

The nearest MRT station is Sam Yot, about a 15-minute walk away. Tuk-tuks and taxis can also reach the temple easily from Khao San Road or the Grand Palace area.

Its centerpiece is the stu ing Loha Prasat (“Metal Castle”), a rare multi-tiered temple adorned with 37 metal spires symbolizing the virtues toward enlightenment .

"Beautiful temple which befits its nickname of Metal Castle. The spires are exquisitely designed and the whole structure stands majestically as asymbol of Thai creativity and craftsmanship.
