Dallas founder John Neely Bryan built his trading post on the east bluff above the Trinity River on a site that is now the southwest corner of Commerce and S. Houston streets, currently occupied by the Federal Building. The log cabin was twice enlarged, and after Bryan sold his interest in the town site in 1853 to Alexander Cockrell, the third cabin was moved to the courthouse square to make room for Cockrell’s new house (not extant). This single pen, without the dogrun and porch, may be one half of Bryan’s third cabin, reconstructed from some of the original materials (the provenance of this replica is uncertain). The surrounding city block, known as Founders Plaza, was landscaped and paved in 2013 by the county for the fiftieth anniversary of President John F. Kennedy’s assassination.
