TEASER ANSWER

For crimfic reader and any others the answer to the teaser was the Atheneum at Historic New Harmony in Indiana.

From Wikpedia:

New Harmony, formerly named "Harmony," was built by the Harmony Society, headed by George Rapp (also known as Johann Georg(e) Rapp). This was the second of three towns built by the German religious group, known as Rappites. When the society decided to move back to Pennsylvania, they sold the 30,000 acres (121 km²) of land and buildings to Robert Owen, the Welsh utopian thinker and social reformer, and to William Maclure for $150,000, who then changed the name from "Harmony" to "New Harmony." Owen recruited residents to his model community, but a number of factors led to an early breakup of the communitarian experiment. The other two towns built by the Rappites were Historic Harmony in Harmony, Pennsylvania, and Old Economy Village (originally known as Oekonomie) in Ambridge, Pennsylvania.

Robert Owen was the Welsh connection, and the name New Harmony is appropiate because it is a very peaceful town. In Southern Indiana, if you avoid Interstate 64, you can drive for miles on quiet country roads through beautiful farmland and interesting small towns. The only snag was that someone put a Quilt Museum in Paducah KY, between the Lincoln Boyhood Home in Indiana and Shiloh Battlefield in Tennessee.

I shall be telling this with a sigh Somewhere ages and ages hence: Two roads diverged in a wood, and I-- I took the one less traveled by, And that has made all the difference...
