I found this article and want you read it
When you reach this Holy Buddhist place, the first thing you will notice is business (left hand side picture), as usual everywhere in Thailand. To reach the Temple of Doi Suthep, climb the stairs (see the right hand side picture) for the best experience.
There has been a kind of rail-elevator, that has been closed down after an accident. It was not in operation in 2004. I do not know if this elevator has been re-opened ever since. There are about 300 steps to climb. The reward is more than worth the effort. You will see a beautiful Buddhist Temple and you will experience a beautiful view. While climbing the stairs, you should pay attention to the giant dragons on the sides of the stairs (they appear already downstairs; see the right hand side picture).
How was the spot for this Temple chosen? When the Temple was being planned, about 600 years ago, the Buddha relics, to put inside the Chedi of the Temple, were put on the back of an elephant. At the spot where this elephant would stop, the Temple was going to be built. The elephant stopped at the spot where the Temple has been built, which is not the top of the mountain, but roughly just halfway the mountain.
The Lanna Kingdom was a Kingdom in the North of Thailand, at about the same time as the Kingdom of Ayutthaya was in charge of Central Thailand.
The chedi is surrounded by four golden "umbrella's", one of which can be seen on the picture. They seem to have a function, similar to the "corner stones" that you find around ever Buddhist Temple (Wat) in Thailand.
