Why go, and how to do it well

Skip this one and you miss the strangest silhouette in the Old Town. The Loha Prasat, or metal castle, rises 36 meters in seven tiers topped by 37 metal spires, one for each of the virtues that lead to enlightenment. It was the first building of its kind in Thailand, and the earlier metal castles it was modeled on, in India and Sri Lanka, are long gone. King Rama III founded the temple, Wat Ratchanatdaram, in 1846 for his granddaughter, which is where the name, the temple of the royal niece, comes from.

Climb it. That's the point of coming. A spiral wooden staircase runs up through the middle to an open top level, where you can walk all the way around for a view over the Golden Mount, Democracy Monument and Ratchadamnoen Avenue. Foreign visitors pay ฿20, Thais ฿10, and children under 15 go free. The grounds stay quiet even when the big temples nearby are packed, and late afternoon light throws the spires into relief.

It's open daily from 08:00 to 17:00. Cover your shoulders and knees, as it's a working temple. The Golden Mount is about 350 meters away, Democracy Monument a similar walk the other way, and the Rattanakosin Exhibition Hall next door has a rooftop view back over the spires. The Khlong Saen Saep canal boat stops at Phan Fa pier a few minutes away, and MRT Sam Yot is about 15 minutes on foot. Jay Fai and Thipsamai are both a short walk for lunch.

When we talk about grandpa’s gift to the grand-children, we probably think of money, toy, book, pet, music instruments. Well, Thailand King Rama III built Wat Ratchanatdaram Worawihan, Loha Prasat, for his granddaughter, who became the first consort of King Rama IV the Great and was commonly known as Queen Sommanat Wattanawadi. It is called Loha Prasat because it means iron or metal castle or iron or metal monastery. Loha Prasat, a royal temple, is firstly conceived and built [but unfinished] in 1846 and finally completed in 2007. It is considered the first metal castle style temple in Thailand. It was constructed into a 7-storey building with 37 golden-color castle peaks, which refers to the 37 Bodhipakkhiya Dharma in Buddhism. The top of the castle on the 7th floor is where the Buddha’s relics are enshrined. The visitors can walk around the 7th floor and have 360-degree view. For any visitors to the Temple, they will all impressed by the design of the building when natural sunshine or sun light can come in from 4 sides of the building wall, and every piece of the walls does have some Buddhist study or meditation reading or phrases for reflections. It is the only remaining Buddhist temple in castle peaks style in the world, when two other similar temples in India and Sri Lanka have been damaged. The Temple can be accessed by taking Bangkok MRT to Sam Yot Station, BL 30. The entrance fee for entering the 7-story building is $20 BAHT for foreigners, while Thailand citizens are free.

This Buddhist temple set in the heart of Bangkok is a thing of beauty. Do not rush your time here, it is a place to stroll, stop, admire and contemplate life. A true work of art and a stunning example of Buddhist and Thai culture that must be visited when in Bangkok.

Went there Saturday late afternoon, less crowded. Sun is getting down which creates a beautiful background. It's quite peaceful walking around the temple.

Tips for Visiting Temples & Culture

Mind Your Feet

Never point your feet at a Buddha image or a monk — it's considered deeply disrespectful. When sitting inside a temple, tuck your feet behind you or to the side.

Ask Before Photographing

Exterior photos are almost always fine, but some interior halls prohibit photography. Look for signs, and never pose irreverently with Buddha images — it's a legal offense in Thailand.

Go Early Morning

Big-name temples are dramatically less crowded in the first hour after opening. You'll also avoid the worst of the midday heat and get softer light for photos.
