Next to the fort on the eastern side is Wat Sangvej Printing School. This century-old building is the place that produced the early editions of the textbooks of Thailand. Behind the building is the quiet Klong Bang Lamphu (Bang Lamphu Canal) which remains a good place to relax. The canal was dug during the reign of King Rama I in the year 1782 by 10,000 Khmer labourers. Pridi Phanomyong, Thailand's stateman, once cruised along this canal and distributed his leaflets on politics that led to major political changes later on.
