What is "felsengarten"

Felsengarten is a historic summer house on Lewis Hill Road in Bethlehem, New Hampshire. The two story house was built between 1896 and 1900, and was the summer residence of German-American conductor Theodore Thomas and his wife Rose Fay. Thomas was an influential figure in popularizing classical orchestral music in the United States during the 19th century. Felsengarten ( German for "stone garden") houses an extensive collection of Thomas' books and papers, and the gardens laid out by him and his wife are still to be discerned in the landscape.

The house and garden were listed on the National Register of Historic Places in 1973.
