The Rotunda at the University of Virginia. According to Wikipedia, “It was designed by Thomas Jefferson to represent the 'authority of nature and power of reason' and was inspired by the Pantheon in Rome. Construction began in 1822 and was completed shortly after Jefferson's death in 1826. The grounds of the new university were unique in that they surrounded a library housed in the Rotunda rather than a church, as was common at other universities in the English-speaking world. The Rotunda is seen as a lasting symbol of Jefferson's belief in the separation of church and education, as well as his lifelong dedication to both education and architecture.”
