Not interested in silk production and trade I was hesitating if to visit this museum at all. But, on our 4th day in Bangkok having nothing else to do as we've visited all other attractions we came here, as I was curious why is so highly ranked.
The house, better say complex of them, as Mr. Thompson bought several is situated by a canal in a picturesque and green environment.
Entry fee is 200 Baht (6$) and you can only visit with a guided tour (in 4 languages). Be prepared for waiting - you cannot buy tickets online which is quite odd, but only on the spot. When we arrived around 11.30AM there was a huge line and we got our spot at 1PM tour. So, consider coming earlier, buy tickets for suitable time and go somewhere else in order not to wait there.
For me, most fascinating was Mr. Thompson's life story. He was born in a wealthy family - his father being a successful textile merchant with strong political connections in US government and mother raising several charity funds.
However, he studied and became an architect (the whole complex you see and visit was made by himself). He joined the army, serving in several parts of the world, when he fall in love with Thailand, and after that he worked in US secret service. Finally he gave up from everything of that, resigned and came back to Thailand to start the silk business, rest is history.
Like everything else he did, it became a huge success. His creations were globally recognized and popular. Customers included European and Asian royalty, Hollywood movie stars,...etc.
At the end of the tour is a shop, however don't expect Thai bargains but rather 5 Av. prices.
