| Pom Thung Setthi (ป้อมทุ่งเศรษฐี)  
Thai. ‘Millionaire's Field Fortress’. Name 
of an archaeological site in 
					
	Kamphaeng Phet 
featuring an old 
	
	laterite 
fort. It is situated on the west side of the 
			
			Ping 
river, and together with the river in the 
past formed a first line of defence against attacks from the west, namely from
Hansawati, i.e. the former 
	
	Mon 
kingdom in 
		Burma 
and the historical archenemy of 
			
			Siam 
during the 
		
		Ayutthaya 
period. It thus protected the old city of 
Kamphaeng Phet, which 
once was an important outpost of 
			 
				 
			
				Sukhothai, and a buffer against attacks from
 
			
        Burma. The city of 
Kamphaeng Phet is located on the east side of the river and its name means ‘Diamond Wall’, 
i.e.
			a ‘wall 
			(kamphaeng) as hard as a diamond (phet)’, 
built to prevent the enemy to go beyond it. The fortress is built as an European 
style star fort, a bastion with a square floor plan and arrow-shaped bulwarks, i.e. angular 
structures projecting outward from the curtain walls of the fortification, positioned at each of the four corners, 
which allowed for fire from the flanks and a offers a better defence of the 
curtain walls. The walls are approximately 6 metres high and whereas the 
distance between the tip of the bulwarks is circa 82 metres, the curtain walls 
measure around 52 metres and at the base have a thickness of about 3.5 metres. 
The 
battlement 
is topped with a crenellated parapet 
that consist of merlons 
called 
bai sema,
which at the base each have 
a horizontal 
loophole or 
embrasure. At 
the bottom, the thick inner walls have large, deep bunker-like niches in the 
form of a house-shaped pentagon, some of which have a single window of the same 
shape in the outer wall. On all four sides, in the 
middle of each  curtain wall, 
is a large gate.  Thung Setthi 
Fortress was reportedly built by the Portuguese, who since 1518 AD, in the reign 
of King 
			      
			      Ramathibodi 
II (1491—1529 AD), already supplied the Siamese of Portuguese guns and 
ammunition. In addition, this king established a Portuguese training corps and 
hired Portuguese mercenaries to fight on his side. 
The fortress is believed to date from 
approximately the 21st—22nd century 
		      
		      
BE, 
which corresponds roughly to anywhere from the early 16th 
to mid 17th century AD.
