Bull visited the United States several times and was met with great success. In 1852, he obtained a large tract of land in Pennsylvania and founded a colony he called New Norway, but that is commonly referred to as Ole Bull Colony. On 24 May 1852, he formally purchased for $10,388. The land consisted of four communities: New Bergen, now known as Carter Camp; Oleona, named after him and his mother, six miles (10 km) south of New Bergen; New Norway, one mile south of New Bergen; and Valhalla in the Kettle Creek area.
