Bangkok is a place rich in culture and heritage. When you are visiting Bangkok, you can go to Sukhumvits, it is an exlclusive district in Bangkok. Here are the museums in Sukhumvits you can visit when you are there.

Kamthieng House Museum, 131 Sukhumvit Soi 21 (Asoke Rd) (BTS Asok or MRT Sukhumvit, then a five-minutes walk north), ? +66-2-661-6470?. Tu-Sa 9AM-5PM. Ban Kamthieng is a 19th-century ancient Thai stilted teak house where you definitely wouldn’t expect it: right in the middle of Bangkok’s high-rises. It was transported from Chiang Mai in pieces and assembled in Bangkok in 1964 to function as the headquarters of the Siam Society, an organization that has the goal of preserving the cultural heritage of Thailand. Beside the house itself, on display are traditional tools, arts and crafts used by Lanna farmers and fishermen from northern Thailand in olden times, as well as a large selection of Thai flora in its yard. There is a heavy focus on the cultural heritage of northern Thailand, as that’s where the house and most of the tools on display came from. The only downside of the museum is that it’s quite small, so don’t expect to spend here longer than 30 minutes (or even 15 minutes if you’re quick). 100 baht.
