Bangkok Fort Phra Sumen
There are 2 forts left in Bangkok from this period, Fort Mahakarn and of course this one Fort Phra Sumen, Fort Phra Sumen was built in 1783 on the banks of the Chao Phraya River and the Banglamphu Canal, it has 2 levels of fortifications for the canons and of course the observation tower.
This fort protected the area up to the northern end of Rattanakosin Island.
Originally there were 14 forts, sadly all that is left of this part of Thai history is the remaining 2 forts, thats progress I suppose.
I suppose being so old it can be excused a coat of paint.
Next door to the fort is a small park called Santichaiprakarn Park, has some seating areas and that is about it.
