Mandovia was laid out as a town in 1858 by Dr. George W. Cooper on the south side of Garnett. Only three log cabins were built on the site. A lithographed map had been circulated in the east and many lots sold. Whenever Colonel W.A. Johnson spoke of the town as having some “historical notoriety” in his history. An excellent lithographed map was drawn up and circulated in the east to encourage people to buy lots in the town.
By 1860 the town had been dropped and only known to live on paper. An addition to Garnett is shown on some maps as the Mandovia addition, on the south side of Garnett from 12th Street south to the South Lake, bounded on the west side by Highway 59 and the east side by Oak Street.
