[2] Built in 1933, the post office houses murals depicting pastoral scenes.

The building's roof is made entirely of terra cotta tiles.

Some of the original murals were removed and lost after a remodeling of the post office in 1960, however two were found recently.

The Federal government took the lost murals into custody prior to them being re-hung in their original place.
