During our visit to Budapest in 2010 we saw this special effect on a façade. The text ‘Terror’ appears on the façade when the sun is shining. It made us curious what it was, but we didn’t visit the building because we were on our way to the Synagogue and after that had to go to the airport. Later we discovered that this building is the House of Terror. The House of Terror is a museum with exhibitions about fascist and communist dictatorial regimes in Hungary in the 20th-century. The frame for the museum gives a sharp contrast to other buildings on Andrassy Avenue.
