Jim Thompson House. This artfully designed complex of six teak buildings is the former home of an American architect-turned-intelligence-officer (OSS, now the CIA) who was posted to the Thai capital in the waning days of World War II and then moved there permanently. Thompson disappeared in the jungles of Malaysia in 1967, but his house remains as a monument to traditional Thai architecture. Admission is 100 baht. Afterward, had lunch in the lovely riverside restaurant. Jim Thompson was also responsible for restoring the silk industry in Thailand.
