To celebrate the diplomatic affiliation between Thailand and Turkey, which was inaugurated on 12 May 1958

Lohaprasat of Wat Ratchanaddah in Bangkok and the national flag of Thailand

The  Lohaprasat (structure with a spire in metal) was commissioned by Rama III, to commemorate his granddaughter princess Sohmanat Watana Wadih, who later became the first queen of Rama IV. The Thai version has seven storeys with thirty-seven spires surrounding the outside, one on the top, twenty-four on the second floor, and twelve on the fourth, and which represent the seven sets of thirty-seven qualities that must be observed in order to attain Enlightenment as described in the Bodhi Pakkhiyah Dhamma discourse given by the Buddha. The Thai Lohaprasat of Wat Ratchanaddah is the only one of its kind still intact today.
