Roberto González Goyri (1924-2007)
This incredible concrete relief mural was created by Guatemalan painter, sculptor and muralist Roberto González Goyri for the west-facing facade of the Bank of Guatemala in 1964-65. The Mayan/Pre-Columbian inspired design made up of 3 sections each measuring 7.2 x 40 meters with relief-depths ranging from 5-12", was cast in situ using multiple wood forms which measured 1.22 x 2.44 meters each. The Bank has a document that explains the mural in depth but it is in Spanish- see it here.
There is also a mural on the east-side of the bank designed by Dagoberto Vásquez; in fact most of the buildings located at the Guatemala Civic Center (where the bank stands), are adorned with relief murals.
