The King of Thailand Birthplace Foundation, a nonprofit corporation and public charity incorporated in 1998 under 501(c)(3) in Massachusetts . KTBF is comprised of Thai and American men and women who believe in cultural exchange, community service, and historic preservation.

Our objective is to establish and maintain a Cultural Center recognizing the birthplace of His Majesty King Bhumibol Adulyadej of Thailand who is the only monarch of a foreign country to be born in the USA , Mount Auburn Hospital in Cambridge . Our major activity is to promote cultural exchanges. The program has been highly successful.

In addition to the joint project with the city of Cambridge to improve King Bhumibol Square, KTBF is also in a process of establishing KTBF Library and Museum in Gloucester in honor of King Bhumibol and his family who used to live in Massachusetts from 1916 - 1928. The owner of the house where HRH Prince Mahidol stayed when HRH first arrived in Massachusetts has donated two rooms in their home to be used as a library and museum purpose. Another project is developing the Thai history path by placing the bronze plaque at each house where HRH Prince Mahidol and Princess Mother used to stay from 1916 – 1928 in Massachusetts .
