Khun Phaen’s house is located on Pathon Road, Tambon Pratuchai, near Wihan Phra Mongkhon Bophit, which has a total area of 5 rai, is located within the area of the Ayutthaya liquor plant adjacent to Chedi Phra Si Suriyothai.
Within the area is a common building, a Somdet Phra Si Suriyothai pavilion, a mound with marble Semas (boundary stones of a temple) aged over 400 years where the fragmented parts of Buddha images taken from Wat Phutthaisawan were buried, etc. The Liquor Distillery Organization, who sponsored the construction of the park, wished to devote all good deeds in transforming the former inner part of the royal compound to all of the late kings who used to live here. King Rama IX graciously named the park Suan Si Suriyothai on 25 May, 1989 and conferred the park to Her Majesty Queen Sirikit on the eve of her 60th anniversary. The park is open daily to the public from 9.00 a.m. until 5.00 p.m.
