Various stupas, in Thai known as Phra Chedi, from around Thailand:

Wat Yai Chai Mongkon in Ayutthaya

‘Great Temple of the Auspicious Victory’, a temple in Ayutthaya, which was presumably built in the reign of King U-Thong, not so long after the founding of the capital in 1351 AD, and was initially named Wat Pah Kaew.  It was built to hold the ashes of Chao Kaew and Chao Thai, who both had died of cholera. Its name was changed in 1593 AD after King Naresuan in 1592 had a bell-shaped chedi built by royal command, in order to commemorate his victory over the viceroy of Burma, whom he had defeated in a duel fought on the backs of war elephants in Nong Sarai near Suphanburi . The chedi of Wat Yai Chai Mongkon is the tallest in Ayutthaya province and is enclosed within a boundary wall that on the inside has a gallery with rows of Buddha images, all seated in the bhumisparsa pose. The principal Buddha image of Wat Yai Chai Mongkon is made of sandstone and is seated in the bhumisparsa pose.

Wat Phrathat Haripunchai in Lamphun

According to legend the temple's main or central chedi was built in 1064 AD by King Athitayaraat , the King of Haripunchai, to house some relic bones of the Buddha. The main chedi, containing the relics of the Buddha, is called Phra Borommathat Haripunchai.
