Step into an American railroad terminal at the turn of the 20th century or imagine a Roaring ’20s ball. A stay at one of Carlson Hospitality’s historic U.S. hotels offers all the desired modern comforts while evoking the romance and spirit of ages past.

The allure of an arched entry, the shine of a polished marble floor, the strength of a towering column: You needn’t be an architect to appreciate the qualities of a beautiful building. And historic sites are almost always beautiful in some way. They are treasures of the past, reminders of how society continues to change.

A program honoring such special places, the National Trust Historic Hotels of America, recently announced the addition of two Carlson Hospitality Worldwide properties to its ranks, bringing the total number to three. Member hotels are judged for architectural integrity, preservation efforts and historical significance.
