Picasso's Regjeringskvartalet murals are a series of murals designed by the Spanish artist Pablo Picasso in the late 1950s and the early 1970s. He designed five murals (The Beach, The Seagull, Satyr and Faun and two versions of The Fishermen) for the Regjeringskvartalet ('Government quarter') buildings in central Oslo, Norway. The designs by Picasso were executed in concrete by Norwegian artist Carl Nesjar, and were Picasso's first attempt at monumental concrete murals. The buildings onto which the murals were executed are known as the 'H-block' or Highrise (1959) and 'Y-block' (1968); they were designed by the Norwegian architect Erling Viksjø. The largest mural, The Fishermen (1970) is on the façade of Y-block. Picasso would later create works in a similar vein in Barcelona and Stockholm
