The link in the most recent comment by JohnInDC is one to a site with links to sites describing the U S Capitol Whoever designed that link may not have known that the plan was Ellicott s rather than L Enfant s That also seems to be the case at Arlington Cemetery where a historical marker in front of L Enfant s grave illustrates Ellicott s Plan rather than L Enfant s original plan As L Enfant objected to Ellicott s revisions in his letters he would probably not be very happy about this misidentification Fortunately his grave is covered by a slab containing a copy of a portion of his own plan However the public usually only sees the copy of Ellicott s plan or revision As to the caption of the pictures on the Wikipedia pages the people who have commented above should all visit the website describing the Library of Congress holdings of L Enfant s and Ellicott s plans in the Library s catalog at The summary of the holdings states Summary Includes plans by Pierre L Enfant facsimile maps published in 1887 by the U S Coast and Geodetic Survey and Andrew Ellicott 1792 and In its most definitive site the Library of Congress therefore identifies the plan in the Wikipedia pages as Ellicott s plan I will leave it to others to revise the caption on the plan in the Wikepedia pages as I do not want to revise it again myself
