HARTFORD, Conn. - Two Connecticut properties are among 10 nationwide being designated as historic landmarks.

The James Merrill House in Stonington and the Steward's House in Cornwall are among the properties recognized as having exceptional value to the nation. They were announced by the U.S. Department of the Interior and the National Park Service.

The other sites are in Wyoming, Indiana, Michigan, Wisconsin, Mississippi, Florida, New York, and Ohio.

The 10 landmarks include properties honoring the nation's civil rights and lesbian, gay, bisexual, and transgender history, federal officials said.

"These 10 new national historic landmarks reveal important pieces of our nation's diverse heritage through art, architecture, and stories of community and identity," said U.S. Secretary of the Interior Sally Jewell. She said the designation "ensures future generations can trace, understand, and learn from these properties, which join more than 2,500 other landmarks nationwide."

The James Merrill House was home to writer James Merrill, who won every major U.S. award for poetry and wrote about gay life.

The Steward's House, also called the Foreign Mission School, provided an evangelical education to students from about 30 countries in the 19th century and prompted debate about interracial relationships.

The other historic landmarks announced are the Ames Monument in Albany County, Wyo.; the Athenaeum, also called Das Deutsche Haus, in Indianapolis; Gaukler Pointe, also called the Edsel and Eleanor Ford House, in Macomb County, Mich.; Man Mound in Sauk County, Wis.; the Mississippi State Capitol in Jackson; the Norman Film Manufacturing Co. in Jacksonville, Fla.; St. Bartholomew's Church and Community House in New York; and the Zoar Historic District in Zoar, Ohio.

St. Bartholomew's Church, federal officials said, is a pivotal example of the work of architect Bertram Grosvenor Goodhue and an outstanding example of early 20th-century ecclesiastical architecture.
