The Royal Legacy

The Only Monarch Born in the USA

King Bhumibol Adulyadej is the only monarch born in the United States, having been born at Mount Auburn Hospital in Cambridge, Massachusetts, on December 5, 1927.

The Birthplace Monument was installed on November 18, 2003, at the intersection of Eliot and Bennett Street at Harvard Square. This historical landmark continues to attract visitors from Thailand and America who wish to express their respect and gratitude.

Trail of Thai Royalty

The Trail of Thai Royalty in Massachusetts and New Hampshire honors the King’s family by marking over eleven historic sites where they stayed between 1916 and 1928.

Thousands of Thai people make the pilgrimage each year to visit these important places and feel a connection to this unique piece of history.
