The Post Office Cabin is a small house converted to showcase the bank of letter boxes and clerk window that was installed in the first US Post Office in Live Oak County opened in Oakville - the County seat at that time.  It dates back to the 1850's and remained in use until the 1980's.  It is a Designated Texas Historic Landmark.   

At it's re-dedication in July 2009, many of the families that used these PO boxes to receive mail thru the generations ,still remembered their combinations and were able to unlock their box!  This is truly a local treasure as well as a Texas treasure!
