Si Phum Corner
Standing at the northeast corner of Chiang Mai's ancient walled city, Si Phum Corner is a well-preserved remnant of the fortifications built by King Mengrai when he founded the city in 1296. The old city was designed as a square, moated settlement, and this corner bastion is one of the most intact sections of that original perimeter, making it a genuine piece of Lanna-era history rather than a reconstructed attraction. It sits within the Si Phum neighbourhood of the old city and is easy to reach on foot from Tha Pae Gate. Visitors can walk along the moat-side path and take in the stonework up close, with the surrounding area offering a relaxed, unhurried atmosphere. The contrast between the ancient walls and the everyday activity of the neighbourhood gives the site an authentic, lived-in quality. It is particularly atmospheric during the Yi Peng lantern festival, when the old city comes alive with celebrations. Good to know: Si Phum Corner is an outdoor historical landmark on a public street, accessible at any time of day. Early morning visits are quieter and more pleasant in the cooler air. Visitors are asked to read the informational signage on site and to refrain from climbing on the old walls, as the stonework is a protected historical structure. The location integrates naturally into a walking loop of the old city's four corners, all of which are worth seeking out.

Visitor Reviews
The ancient walls of Chiang Mai. You can see history all around the city. To all the foreigners that visit this sight. Read the signs and be respectful, and stay off the old wall.
Well preserved north east corner of old city wall.
First a bit of history - Chiang Mai was founded by King Mengrai in 1296 and designed as a square, walled, and moated city, entirely contained within the moat-and-wall perimeter. This area, now known as the Old City, served as the capital of the Lanna Kingdom. The area was completely surrounded by a massive, tall brick wall, with the moat as a defensive barrier against threats. While most of the city walls have disappeared, the moat remains, and the area within is still considered the "Old City" or historical center of Chiang Mai. At each corner there are the remains of a fort or bastion that may be of interest to tourists that are interested in history of this area. They can be viewed from outside the old city or from inside, but be careful of traffic you're doing this. You are not allowed to climb on the bastions or parts of the old wall. The bastion's are lit up at night and are far more attractive to photograph then. Si Phum Is the bastion at the North Eastern corner. Many people find this the most photogenic of the bastions because it has sunk a lot, which shows vividly in the brickwork. Also on the inner side of this bastion is the city pillar shrine of Si Thammerat.

Tips for Visiting Temples & Culture
Dress Modestly
Cover shoulders and knees at all temples. Carry a light scarf or sarong — some temples lend wraps, but not all. Shoes come off before entering any building with a Buddha image.
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.
