The Lyon Block is a historic building located in Maquoketa, Iowa, United States.

Brick is also the main design element of the building as found in the rhythmical arches above the second floor windows.

The color and texture of the wall surface are now the important decorative features and not that which was applied to it.

[2] The man floor storefront has been altered, but the significant historical elements of the building have been left in place.
