Y-Block

The Y-Block was a building in Oslo, Norway, extant from 1970 to 2020.

The building, designed in a Brutalist style by Erling Viksjø, was part of the Regjeringskvartalet (Government Quarter) in the centre of the city.

It was one of few sites with murals designed by Picasso, along with the Château de Castille in France and the Col·legi d'Arquitectes de Catalunya in Barcelona.

In 2020, following intense public debate, the building's murals were removed and the remaining structure was demolished.

The murals are planned to be incorporated into a replacement building.
